Hey, @drinktigermilk! Unfortunately, this is the first post that I've seen around the Support Community regarding WiFi calling taking a back seat to cellular after updating to Pie. We're still working to get answers on why this is happening and what we can do to fix it. In the meantime, we're using this thread: Official Android 9.0 Pie Discussion Thread to track user-reported issues related to Pie. When we have more info, we'll be sure to post it over on the linked thread. This thread doesn’t exist and this link is broken. Also this isn’t a solution.
This is happening with my Galaxy s21Wifi preferred keeps switching back to cellular preferred. I’m missing important calls because I work from home where I don’t have great cell coverage.
