Apple TV app stalling on Panasonic TV

Watching the new Apple TV+ app on my 3 year old Panasonic 4K OLED TV and, despite a good internet connection, the Apple programmes often stall, hesitate and even restart. Very frustrating. While in this state, maybe after 30 minutes of good viewing, I check the the internet link and it’s all running at full speed. My deduction is that either the Apple servers are stalling, which I think is unlikely, or the new Panasonic Apple TV+ app is buggy. Anyone else have a similar problem? Or even a solution?

Currently trying to watch the 3rd episode of ‘Suspicion’ and again it’s just restarted this episode…

A frustrated thanks,
