After Updating App - No longer able to activate " HMS ", Remotely?

Is it just me or has anyone else experienced, a lack of remotely ( by android phone).
The ability to activate or deactivate. My Home Monitoring System (HMS) ?

I’ve tried -
Updating Ph’s Wyze app (latest version last wk)
Checked to see if, any Wyze device on the App, need updating (none necessary)
I force stopped the Wyze app (only works or that particular moment)

Any other suggestions, of what I may be missing ?

My mode switch always fails from my app
both at home network and remote
lat time it worked was about 2 weeks ago
