For several weeks Shaw Blue Curve (now Ignite) TV app on Pixel 4a has not worked.  Any selection I make - either live TV or on demand - produces the following:

"We're Having Some Trouble::15106

We're sorry, something unexpected just happened.  Please try again"

I've tried everything I can think of - deleting & reinstalling app, clearing data/cache, etc.  Nothing gets it to work.

Any advice appreciated
