Telus TV (Pik TV) - CTV and Global channels keep dropping

This appears to be a general issue with the Telus TV+ application that runs in a browser.

As of a couple of weeks ago, a number of people have reported this issue, see: https://forum.telus.com/t5/Optik-TV/Telus-Tv-on-a-Mac/td-p/137522

For me, after 4 to 10 minutes, the show I'm watching on my PC, using Edge, closes and I'm returned to the Guide.
Interestingly, when I used Firefox it streamed a TV channel for much longer, but after 30 min I encountered an error message "This browser is not supported" and when I clicked OK on the dialog the app went back to the Guide.

I would guess Telus' development group has a missing regression test and released this issue with a recent update on the in-browser application - they'll have to fix it on their side.

Edit add:
Using Android, Apple TV, etc. does not present this issue - only using Telus TV+ application in a browser is presenting this issue. 

Edit 2 add:
Since it's been a week since I last tested this, I tried again today and I discovered the problem is likely resolved.   I watched a program for an hour with no issues today (using Edge).
