I use a Brave browser, but when I use that, the rotation follows correctly. But when the "Added to Homescreen" is the only place that does not follow the correct set of my phone.
So most likely the issue is right there in the home screen app.
This issue happens in the brave browser before, this is a bug >
Auto Rotate < but mostly will be fixed when they reopen close the application. this bug happens in
1.13.85 version, but when happening in stake platform only, better do not add in your home screen, just bookmarked it on your browser.
