2 V4 cams stopped recording events to cloud

HI New here to Wyze , i have put two camera to monitor two terrariums at night under IR b/w with spiders in them. The app was recording events which were appearing in the cloud but since the end of 20th Sept it hasnt recorded or sent any videos to the cloud . Any suggestions what is wrong??

I initially signed up for a free trial for one v4 cam but have since bought another and upgraded the cam plus for 2 cams. The subscription for the one cam i cancelled in google play is showing still but expiring on the 17th OCT and i assigned both cameras to the new subscription for 2 cams.

Thanks for any help.
