I have Google Fi for cell service and live in a rural area with 0 cell service at my home. I discovered that having Tailscale enabled causes phone calls to not work because it always tries to fall back on cellular network, which it can’t find because there is no signal. Turning off Tailscale and calls work fine.
My phone is a Pixel 4a running Android 11.
Is anyone else experiencing this? Is there a work around or more information I should grab to debug?
