In Progress
When I try to search the material (typing the heading or 'fk4ndz8f') I can't find it. But when I type the address it works; https://www.geogebra.org/m/fk4ndz8f
I've checked many times and the worksheet is public. I also tried to register with new account and had the same problem. I can't figure out what I'm doing wrong here.
Another problem: when I try to sign in with GeoGebra 3D android app with my phone, it just shows blank screen. I also tried this with different accounts and it doesn't help.
The same problem
