I have the same issue on iphoneX with the most current version of the app. I reached out to technical support and created a ticket - I suggest everyone does the same by going to the support tab and then clicking on the lower left link CLICK TO CONTACT TECH SUPPORT.
I installed the firmware update yesterday evening at 7pm PST - the install for all 3 of my cams worked flawlessly. HOWEVER, after the install my notifications to my phone went from normal to sporadic. Although it shows all the videos in the notifications tab of the app, I get no on screen notification.
Then, at 12:20pm PST today (2.16.18), all of my video notifications are yielding the following error: “The video Clip doesn’t exist in the cloud or is waiting to be uploaded”.
Unlike ROBERT, who posted at 2:35pm that his videos are becoming available - Mine are not… Everything seems to have ceased at 12:20pm PST!
Here are the steps I have taken for troubleshooting:
unplug all cams, allow 30 seconds, plug back in.
log out of app, quit app, relaunch app, log back in
log out of app, reboot phone, log back in app
I hope the information I provided is found useful to the Wyzecam team and the people in this forum. I will continue to search for solutions. If i find something I will come back to this forum with a post.
