I just bought a Marshall code and found the apps on iOS do not work. Research says that the problem is the app need s to be updated. When are you going to update the IOS apps ?  

I have spent 4 Hrs.  at least trying everything and I have actually used this App to control my code 25 for about 15 min.This App does not work. The code interface is bulky. I love the sounds but it is such a pain to program it is hardly worth it. Marshall should supply an App that actually works with this Amp.  Marshall has a good amp but gets a 0 on its app. What a waste of time. Too bad. I will tell everyone not to get this great Amp because the App that is supposed to work does not. Come on Marshall get with it. I am let down with your products.

I know this forum has this question asked a number of times, and the reply is always to delete the app and re-install.  I've done this multiple times, and it never solves the problem.  In fact, I had this app successfully installed on my iPad a few years ago, and hadn't used it latey.  When I use it now, I get the same message.  

Context3d not available! Possible reasons: wrong renderMode or missing device support

I googled this message and found out that it's related to Flash.  Apple has discontinued all support of Flash on iOS devices.  So my educated guess is that you need to re-vamp this application to not use any Flash programming.  No ammount of deleting and reinstalling the app will ever solve this problem.  You need to update the app.

Hey all, Just received my Code 50 yesterday from Amazon and I cannot get the eq knobs to work in any preset. I can adjust the eq through the gateway app but when I turn the physical knobs on the amp nothing happens. Is this normal? how can I adjust the eq on a preset without using the gateway app?

Hi,

Just received my Code 25.

I can't download the Gateway app on Google play store (Android) as I get a message "Your device is not suitable for this app" or something along those lines.

I use a Huawei P9

Any thoughts?

Thanks in advance

Code 50 does not connect to the gateway app. Iphone 11.

Marshal code 25 has stopped syncing with the cloud. But there is a bluetooth connection.
There are 169 presets saved in the my gateway cloud that is some are repeated and cannot be deleted. Help me please!

I am currently connected to my amp on Bluetooth but I can't get it to connect in "My Gateway". Please help. 
Also When I attempt to register my amp. It AutoFills with "CODE25" information. 

I've purchased this item before and didn't have this issue. What are my options?

On the Gateway App, if I login with my friends account to try his presets on my code, it doesnt sync.  My gateway app on my phone shows he is logged in, and that it has synced, but the presets are just listed as the ones I had on my phone.  

I didnt realize that reset factory presets meant I'd lose the app presets, i.e. EO34 Heaven and Slapback.  How can I get those all back?

after several attempts I still cannot connect the queue with the gateway app. are there any steps I don't
know or is it just a compatibility problem? who can help me?

Hello,

Recently I bought a Code 100 and I've connected it to my phone (Samsung s10). 

When I save and store a new preset via app or amp, it stops playing completely. After a restart, the preset is saved and it starts to sound again.

Is there a way to prevent the "stop" of the amp? 

Thank you all.

I want to keep my own presets on the gateway app but restore the amp presets to factory settings.  Is this possible?

I have created a new preset using my gateway app. It appears in the preset menu on the amp but the sound has not changed. Any advice appreciated.

Sorry because my Englis is not very good.

I have a problem : The Marshall Gateway is no longer available on Google Play ... how can I download it?

It's impossible to use Gateway with the last version of iOS. All I have when I open the app is"context 3D not available! Possible reasons: wrong renderMode or  missing device support."

what can I do?

thanks

I created several presets on my Code 50 and named them.   When I log on to the site, however, my Gateway does not show these presets.  It shows the original factory presets.  How do I get my own presets backed up on to my Library and Gateway?
