3CX Phone App seems not reliable at all

[Sampl]

Hi, we are having issues with the 3CX app. Most of the users that have it on their phones pretty much never hear them ring. They will receive a missed call email without hearing their phone go off. I do notice that when the app is already on screen it will ring reliably but is not really an option is it.

Enable PUSH for smart phones is ticked for all of them and have made sure that their DND settings exclude 3CX.

This is for Androids and iOS users from galaxy J1 2016 to s10 and from iPhone6 to X also a few Huawei's.
Tablets, laptops, pc's wired and dect phones all ring and do as expected (even our warehouse android scanners work as expected) it is only on smart phones (their personal phones)

Might anyone have a suggestion what more to look at?

Yeah, push notifications would be a great idea, in my opinion.

Guys, Push notifications is always there. Check under the Status of your extensions, in the rules there's a "Accept Push notifications", it has to be checked. No this is not the same as under Phone Provisioning.

Also, make sure you use V15.5 U6 or V16 to use the mobile apps. Earlier versions are no longer supported.

It can not be shown because of different versions, that's right. When I was implementing notifications via sms bulk services, first of all I've said customers to visit certain settings and check all the options needed, because there is no profit from any option, if it's not enabled from user's side.
