eufycam 2 no notifications, recording, or motion detection

I got my two eufy homebase and two eufycam2s on Sunday. Worked a treat with motion detection, video recording and notifications. One of the main reasons for my purchase was to keep an eye on my dog while I was away from home as he has just had major surgery to remove a tumor. On Tuesday there were no notifications, recordings and testing motion detection no activation on the cameras.
I have read the forum. Several times I have reformated the sdisk, reinsntalled the software, reset the homebase after disconnecting the cameras. Nothing works on the system except for live view.
Any ideas? Or should I just return the system for a refund. So frustrating wasting time on a brand new security system that should work.
