Video Doorbell 3 - Frequently (multiple times a day) goes into "Update Mode" when it is clearly already up to date

We have 16+ cameras and doorbells, but only the Video Doorbell 3 (battery) models have this issue. Ring tech support has no options to resolve it or any understanding of it. When our two Video Doorbell 3's detect motion or record live video, they go into "Update Mode" right away, and this happens about 75% of the time. I suspect it is a software bug. The doorbell and camera functions continue to be able to ring and show video, which strongly suggests the hardware is fine. Our other doorbells are other/different (battery) models. Signals on all are excellent as is their battery charge. What to do? Thanks I've done all the trouble shooting requested and no luck. I'm told the firmware version should be 12.0.38, yet one shows as 8.0.47 and the other 8.0.51g.
