"Sorry, but managing extensions isn't supported on this device" message appear when trying to add widget integrations

[suzdaleva]

Hello, I have encountered the following behavior: when clicking on "Add Matrix apps" on the menu inside a chat room, error occurs with the message "Sorry, but managing extensions isn't supported on this device. We're working on it..."

Steps to reproduce the behavior:

1. Go to any chat room.
2. Click on a dot menu, select "Add Matrix apps".
3. See screen loading for a few seconds, then loading fails with the message "Sorry, but managing extensions isn't supported on this device. We're working on it...".

Expected behavior App allows users to manage widget integrations. As far as I understand, there used to be a way to create a new widget with a link or edit/delete existing widgets.

Upstream relevance

• Does this issue exist in Element Android? - Yes.
• Our team works on a custom widget that is supposed to be integrated in the app in the future. Thus widget integration is kind of a crucial feature for us. Could you, please, let me know whether this feature is currently disabled for all Android devices or is this just a case for some users? If it is globally disabled will it be restored any time soon? Thank you!

I can reproduce. This looks to me like some web page returned by scalar.vector.im though, since it only shows up after accepting terms and conditions for scalar, and I can't find the strings from that message in the Android source code (so I guess it's not disabled form the Android side anyway). As this issue also happens for Element, better to ask them though, I won't touch that.
