VTO 3211D-P2 and GDMSS Plus.....working and not working!!! Why????

[alessandro0811]

good morning! I have a VTO 3211 2 buttons, everything works smoothly except push notifications with the GDMSS PLUS app. I did everything according to the manual here's what mis kills:

• on my phone (honor 10), notifications arrive when "he wants" (2 notifications out of 10) (iliad operator)
• on my wife's phone (realme X2), never received a notification, it doesn't work even dead (vodafone operator)
• on a realme A7 never received a notification
• on an old samsung (J3 perhaps), it doesn't miss a beat (iliad operator)

therefore it does not depend on the operator but on the "telephone" ??? it seems so strange, too strange ...
suggestions and / or advice ???

I also tried the new DMSS app but not even the shadow of notifications. don't you have any idea ??
