Can't sinc cameras after all three stopped working?!?

[McGrade]

System was working fine for about a month and then stopped working all together.
At first I lost connection to the base and couldn't open the app. A day later I was able to open the app but all three cameras were down.
I tried to re sinc each one but no luck. I removed the batteries and placed them back and still no luck.
I even grabbed a pin and reset the base and still no luck?!?
Please help!.

Have you tried to use REMOVE DEVICE and then bring the cameras back as if new with re-sync

Yes I did, and that worked. Thank You!

Not sure how this happened but it was very frustrating.

If this happens again I'm returning the system....ridiculous.
