Tend Lynx Won't Reconect After Power Failure / Restore

Tend Lynx Indoor (1st edition)

I purchased four Tend Lynx cameras and tested them each to see if they would reconnect during a power failure / restore. NONE of them were able to reconnect to the internet. For each, I had to set them up from the beginning to work. 

My two Tend Minion Cams re-connected with no problem, as they always have. I just purchased the Lynx cameras and will return them if they can't reconnect after a power failure.  Used in a second home hours away, I need them to return online after a power failure.

Does anyone have any experience with this?  Thank you!
