Amazon Prime Video on SmartTV

I am experiencing the same issue - all apps EXCEPT Prime Video play on Sony Bravia smart TV when connected to TM Home Internet (TMHI) but will play when connected to TM Hotspot.  I have 2 Sony TV's and PV will not play on either but all other apps will.  I have also connected to the PV app on my Samsung Galaxy S22 Ultra phone via TMHI WiFi with no issues and my husband connects same on his Galaxy table with no issues.  After troubleshooting with Sony, I was convinced it was strictly a TMHI conflict but since the PV app works on these 2 other Android devices, I am back to it must be a Sony TV issue and/or TMHI.  Both Sony and TM want to point fingers at the other one rather than helping their customers solve this issue which many users are experiencing.
