Same issue on my MaxiSys MS906BT--it was uploading to cloud OK before and I was
able to sent SMS and email no problem--- and not recently maybe 2-3 months it
Stopped uploading to Cloud. I restarted Tablet several times and tried home WiFi and
work WiFi and to iphone hotspot to try different WiFi settings -- but still same problem.
I think its on Autel side something bogged down.
