Here is how I worked around force upgrade in install/setup. This is on iOS, probable works on Android too.
After the setup, it displays this to ask for update:
You have option to “Update now” or “update them all at once”. Since I don’t know which version it will update to for “Update now” option, I closed and restart the Wyze app. After app started, click on the doorbell from Home panel. But before it got a chance to load the live view (and update pop up screen), click on settings (gear icon) → Device Info → Firmware Version.
From here, click Update to update from original version to 4.51.1.7270
After update, click on the doorbell from Home panel. It asks if you want upgrade.
Clicks cancel. Go settings (gear icon) → Device Info → Firmware Version.
Click to update to 4.51.1.8444. But before you do that, disable “Automatic Update”.
After update to 4.51.1.8444, stop. Next version it tries to update is 4.51.1.9341, which is the version we don’t want.
