hi there. Awesome project! I was using cryptpad on my ubuntu touch device and most of it is 'usable' however the whiteboard doesn't work. It loads but it is effectively unusable (doesn't recognize brush, for example).
Since Ubuntu Touch is very much aligned with the principles of CryptPad would love to see all parts working perfectly 🙂
I can help test in the Morph Browser (that's the name of the default browser with an Ubuntu Touch default install)
I'm using a Pixel 3a device currently.
