Dashboard thumbnail view for one camera not updating

I have 8 cameras setup on dashboard. All camera views on dashboard are updating every few mins except one of the cameras. The one camera just shows a static photo of the stickup cam but not a snapshot. Motion is successsfully recording but the dashboard thumbnail view never updates.. The dashboard thumbnail view never updates for this one camera, all the others do. I've tried re-installing app, logging out/logging into the app, removed and re-added the camera, rebooting router. Good device health, 33 RSSI, 100% battery, Good battery and signal strengh are reported in device health report. This is an older Stick Up Cam. Same behavior occurs on both Win10 and Andriod app for this perticular camera. Any suggestions on how to resolve this issue?
