Multiple cameras.. but one camera stalls on playback? can only see screen shot? other cameras are fine

I have Multiple Wyze Cameras in 3 separate locations… and love them all… sadly one camera (original model no pan) doesn’t give me playback? I can see live image… I get notices when movement has happened and I get a screen shot… but when I try and play the 12 second clip I get a spinning icon with 64.1mb displayed? but never the clip? the camera has no card in it… the wifi is fairly quick… signal strength of camera is 3 bars… I have changed settings from HD to SD… turned off sound… etc… live image is always good…I have remotely turned camera on and off… and remotely restarted device… the firmware version is 3.9.4.16 … sadly no one is at location to help me… any thoughts or ideas?
