playing on mobile doesn't work after the website update on 24.04

As the title says, then playing on mobile doesn't work after the website update on 24.04. Just stays like this after rotating my phone: (image added).

Also cannot join an existing game that my friend created via link. Please fix this. I am stranded in Asia with mothing but a phone and too much free time due to the quarantine.
