User A opens up Plex. Everything seems fine. Then User B grabs remote and switches to their own account. The list of media from User A is still present despite it seemingly switching over to User B account. Manually picking a library and then going back to home causes User B’s Continue Watching to properly load.
Children ratings don’t seem to block inappropriate images from showing up this way. If User A is an adult and has adult content on Continue Watching, switching to Child User B will cause adult content to appear on their own home page until it is manually refreshed away.
This is on Plex for Android (latest public version) running on an Nvidia Shield Pro (2019). Plex for Windows doesn’t have this issue.
