Strange - My M34 has the latest August Security patch and it shows 1080p playback on Prime Video

Same here - can't find server after August update and so last checked date isn't updated.

Working ok for me .

I have Amazon Brand- Solimo Basic Case for Samsung Galaxy M34 5G (Silicone_Deep Blue) : Amazon.in: Electronics (one of the few available from day 1). It is grippy and works fine with my edge to edge tempered glass).
