I have 3 Yi indoor dome cameras and I am using IOS. They worked for years watching video on the SD card. They are located in 2 different residences on 2 different networks. All three no longer play back video from the as cards.
It records motion video and you can rewind timeline on all cameras. Once you stop and request playback, it just freezes displaying live video in the background.
What I have tried
Reformatting sd cards
Deleting and reinstalling app on iPhone
Verifying latest firmware
All have not resolved the issue.
I strongly suspect an IPhone software issue
Thank for your assistance
