Prior to the update to Angroid 10 I had no issues with my Galaxy S9 ... I loved it! Now I no longer get text messages displayed on my screen in the Toyota Prius. I have checked every setting I can think of and reconnected my phone multiple times. I can make calls but that is it...please help. T-Mobile says they cannot help me.
I would recommend seeing if there are any updates for the Prius. Have you tried wiping the cache partition since the update?
