After installing the Connect Mobile IOS Beta, both the scale and the blood pressure monitor required finding the WIFI network again.
1. That was successful on the scale, but it lost track of me as the owner and starting upload my weight to the other user we had defined. It also created a second "S2" Bluetooth entry. I had to remove both of them, drop the second user, and completely reset the device.
2. The BPM indicated it was uploading values, but they did not appear in Connect at all, so removed it from Bluetooth and started over.
DISCLAIMER: I think I also updated to iOS 17.4.1 in that same time period.
