System reads offline half of the time?

I have a Vava Cam Pro base and four cameras. Half the time I go into the app, my base station and all cameras read OFFLINE. I had a previous system with a different base and 1 camera; it worked fine. Is this new one just junk? Or maybe a firmware update somewhere along the line made things suck? I think I’m going to have to scrap this system and go with a different brand. Anyone else have similar issues?
