My phone is always portrait locked. Incase it wasn't obvious the phone was mostly unused for this on the table. Only about 30-45mins was active use of voyager.
Will look in voyager settings for rotation though.
I have the same issue and figured the app only worked in the US. I'm in a 5 eeus country but every time I've tried the app I can only navigate to a street. Never a number on that street. Even after download the maps. Most sure what's going wrong.
I don't have a GitHub account. But it's this git version in using. Maybe the playstote version/fdroid build don't have the issue?
