P2 - app usability -investigate- notifications

[nanometrenat]

Using Serval Chat in the field it was noted by users that they were often not getting a notification sound when a Chat message comes in. Notification sounds used to work well for them, but no longer.

It is important to our user base to get notifications.

We tried upgrading their app (to November versions, around 116ish) but still same problem. Not sure if this is a phone/Android setting or something the user can control - but it seems to be happening on a range of phones (e.g. my Xiaomi Mi5 as well as the Alcatel U5 phone that was used by several locals). On my phone the notifications (including sound) were definitely enabled in app settings.

Please investigate and ensure that users get audible notifications when sound is on. Paul has brought back one of the phone models that it needs to definitely work on!
