PlexPass sign-in issue with latest Android app?

On a OnePlus 3, OxygenOS 3.5.6 running Marshmallow 6.x where I was able to sign in previously, now using 5.2.0.477 I get a prompt to upgrade to Plex Pass and if I skip that get no servers and a prompt to activate the one-time streaming on Android. Previously, the Android app was ‘free’ with my lifetime Plex Pass subscrp[tion. Deleted app tried again, no joy. Still signed-in on my iOS app and that works. Confirmed my subscription status is still good via website.

Also tested using a non-Plex-Passed account for myself on another email address I use for testing the viewer experience. No joy.

Both times after ‘signing into’ Plex on the app, I get prompted for the subscription and one-time activation. Clicking the hamburger menu and then Account shows that Plex hasn’t accepted the sign-in. It still says ‘sign in’ instead of showing my username as the currently signed in user.

Kind of baffling.

no adblock or rooting or anything on this. tried the last (nov2016) apk and i get an ‘your credentials have expired please sign in again’ immediately after trying to login.

Weird. Tried again and worked. Must have been something server-side.
