Is every ones android prime pro working OK

[thenozone]

Is every ones android prime pro working OK mine functions but will not recognize that i own the pro version;
when i select "calculator" heading and select "connect to" it just goes back to the cacl main screen.
It shows an option to "upgrade to hp prime pro even though i have a paid copy.
I unsubscribed to the beta testing thinking that might be the problem,( uninstalled and re installed) but this still persists, on 8 device with different processors and up and including android 9.
am i missing something thanks
