Plex stopped remembering progress?

Server Version#: 1.15.5.994-4610c6e8d
Player Version#: 2.012

Hi,

I have ubuntu 18.,04 running my PMS. Ever since the latest update (or possibly the one before also) our Samsung smart TV with player version as above doesn’t seem to remember any progress of TV show or movie watching & defaults to playing from the beginning…

The progress is shown on the preview I. E. It can see I’ve watched maybe 10mins, but doesn’t give me the option to play from that time…

This also affects my sons huawei tablet, but my android phone is fine…

Also seem to be getting transcoder errors & can’t watch anything via the chromecast anymore…

I did try to set up flex-tv recently but that’s not working either atm… Though I’m not fussed about that but mentioned for context.

I tried to downgrade but had the same error with the last version… Maybe I should try the version before?

Any other ideas gratefully received.
