Audible notifications not working in Ring App on Samsung Galaxy 7, 9, 20

I have been on multiple calls and chats with tech support to no avail. Since I have the same problem across 3 devices, all with the most current version of Android and the Ring App available for each individual device, it has to be a conflict with something Samsung or Android . This has been going on since the beginning of the year. Tech support says no one else is reporting this issue, but I find that hard believe given I have three devices that don't work. It's become incredibly frustrating. Because no one has solved this mystery I had to spend money on a chime I shouldn't need to avoid missing people coming to my door and package deliveries. If I reboot the devices, they will work for an hour, 6 hours, 5 minutes. Simply no rhime or reason. Rebooting the devices constantly is the only solution at the moment. Any ideas gang? P.S. All settings have been checked multiple times so just don't go there.
