Thumbnails on mysecurity.eufylife.com

When I log on to the eufy web site to see my cameras on a PC, I use this:
https://mysecurity.eufylife.com/#/camera
It displays all the camera, but as blanks thumbnails.
I need to click on the blank thumbnail for it to show the camera stream.
Then if I click on a 2nd thumbnail, to see that, the first one goes blank.
Why can’t it show live view for all the cameras?
Am I missing a setting somehwere?
Please help!
