on mobile, adding cells with the add cell menu fails with error "Oops, an unexpected error occurred"

[77it]

Describe the bug On mobile, using the notebook while logged in, adding cells with the add cell menu fails with error "Oops, an unexpected error occurred". This happens with any notebook I tried to fork/create. With the same notebooks, shared and opened without a login (e.g. in a private session) adding cells works. With the same notebooks, used while logged in, duplicating cells works.

To Reproduce See youtube video

Expected behavior Adding a cell with the "plus" menu should work for any notebook, while logged in or not.

Thanks for reporting this. It definitely looks like a bug. As a workaround, you should still be able to press and hold the '+' to bring up the cell Menu (on mobile, we just default to JavaScript cells and you have to click and hold to bring up the menu).

This is now fixed.
