Oh well I’m glad it’s partially working for you lithophone.
I just had a go at trying to install the older 7.30.2 version sourced from these forums (Plex for Android - #339 by romancamelia) and Aptoide as suggested by Aleczk but couldn’t get them to install properly (says App not installed), despite uninstalling the latest 8.0.2 version. Also had a go at updating to the latest PMS version 1.19.3.2831 but didn’t make any difference. Seems I’m stuck with this problem until a bug fix is pushed
