It is their service and this happens with them all the time. It takes months to be semi-fixed and then something else goes horribly wrong. Don't waste your time doing the trouble shooting they suggest multiple times. It is not you, it's their servers and bad firmware.
There is a thread about all their issues, that they have now locked, with pages and pages of the similar issues you are experiencing. I would suggest you check it out.
As for finding the builds, on android, open your app, click account tab, then click privacy and legal to see current app version. To see the cameras individually, click the gear box on the live feed, and find the device info tab. On roku tv move to the app, then click the star button to find build number. Not sure about apple products.
That said, there is no manual update anymore, everything is forced, and untested, and rolls out at random times, to random groups of cameras depending on serial numbers.
Save yourself some grief and trust me when I say, it's them as in Roku, not you or the devices, so troubleshooting is a complete waste of time.
