Rive Editor doesn't work on Android mobile/tablet

Hi,

Rive Editor used to work on my phone.
I bought a Galaxy Tab 9 (not just for Rive) and intended to connect a mouse and a keyboard, and work on the editor.

Today, I see that the editor doesn't work on my phone nor on my tablet.

Both Android. 

When I preview a file from the community, or open the editor on my account on my phone or tablet, I just see a gray screen.

Switching to "Desktop site" doesn't work as well.

The browser does not matter.

I am aware there is no official support for mobile, but this was not an issue a while ago, and at the very least I could have tried to use a mouse/keyboard.

I wonder if something changed in the app that might be easy enough to fix.

Thank you!
