Upgrade rendered other cameras useless – Uniden Guardian 2 Review

I currently have 4 of the G955 Uniden cameras/system that I was very satisfied with until I upgraded my app on June 26, 2018. Since the upgrade I can only view one camera because it now states that the signal is too low on the other cameras to view. Never had that problem before. Where I can I find the last version I had before I upgraded? I thought I would be optimizing my system by upgrading but it turned out to be a huge mistake. I would appreciate some support Uniden.
