I got in touch with the Support team, and they asked what the student’s screen resolution was. She’s using the ‘Default for display’ resolution (‘Looks like 1280x800’). We tried each of the four ‘Scaled’ options (in screenshot below), with no change.
We have also discovered that, although she can open and run AppLab projects from the ‘public projects’ section, as soon as she clicks ‘How it works (view code)’ in the ‘Built on Code Studio’ menu, she gets the ‘Rotate Device’ screen again.
We decided to try sending the first project of hers that demonstrated this issue to our phones to see if that made any difference. The app opened normally, and clicking ‘How it works (view code)’ gave the ‘rotate device’ screen. Rotating the phone to landscape mode does get rid of it and let us see AppLab normally.
If she creates a new AppLab project in the browser, it’s fine, but she then can’t open that new project in the Maker App without seeing the ‘rotate device’ screen. So possibly it’s something on her account side? Is there a default orientation setting she could have hit somewhere? I’m not sure that would affect her ability to open other projects, though.
I replied to the support team with this (minus the last paragraph above, because I just thought of trying it), but I’m copying it over here as well just in case anyone else has thoughts/someone else runs into this in future.
