As soon as they decide no complaints are coming in from the Beta testers. Not sure how big that window is, though. That firmware was just released to Beta testing 19 hours ago.
If you want to take a chance and load the Beta firmware, you can do that by going to the Account tab > About > Beta Program > Edit and checkmark the Wyze Watch 44. That will let you see the Beta update the normal way. Don’t forget to uncheck that box when you are done, or it will continually offer you untested Beta updates!
P.S. – I think I had to restart my app afterwards to see the new sort option. May have restarted my watch too, although it restarts itself after the update is complete.
