Wifi calling preferred being reset to cellular preferred. Android / samsung / TM disrespecting our choices.

Seeing many 4 year old threads on this. How does TM / Android keep ignoring user choices and resetting from Wifi Preferred to Cellular preferred?

This is essentially data loss, you are losing or ignoring user choices. We have to have wifi preferred set in our home or we get really bad choppy phone calls. We have elderly parents who are the only people we talk to on the phone. Every third phone call you reset our preferences and we end up having bad call quality. 

Please work with Android / Samsung / whomever you need to to stop disrespecting our choices. 

PS: according to our phones we have TM 5G UC at our house, which shouldn’t have poor quality calls, but I digress.
