I have a Samsung s9 plus if that's any help. Os and play store are fully updated
That update was made a long time ago. Re-check the app store. If you don't see the update, delete the app and re-download it. Works on my S7.
I see the app displays in landscape on my BlackBerry KEYone but on my Samsung S6 Edge it's still in portrait mode (enabled auto-rotate makes no difference) with the latest updates.
It might be an app incompatibility/bug specific to Android Pie.
I'm surprised Samsung Galaxy phones are excluded from testing the landscape feature. Does anyone else use a Samsung Galaxy phone have issues?
Thanks. Uninstalling and reinstalling the app fixed the issue.
