I have three Nvidia Kodi systems. Since V21 all 3 have the same issue
For recorded TV programmes during playback if Stop is pressed, the playback cannot restart from the Stop point. Although the option comes up on the Play menu, the recording will always restart from the beginning
A partial work around is is to bookmark the required restart point before pressing stop. But this only works on the Kodi system that the bookmark was set
I have the Estuary skin and Enigma plug in
