Skype texting on iPhone no longer makes any sounds at all No idea what's going on here, but sometime within the last week or so Skype on my iPhone SE has stopped making any text-related sounds.  Phone calls are fine including ringing and speaking/listening, but notifications will not make a sound.  iOS notifications for Skype are enabled, Notifications within Skype itself are enabled, and I am in "online" mode (not Do Not Disturb).  I have rebooted my phone, quit &amp; relaunched Skype, etc.  Still no joy.

iPhone SE on iOS 10.3.1 (not willing to update to iOS11 so please don't even suggest it)
Skype 8.3.0.51670 (and no way am I updating Skype.  I made that mistake recently on another device and it was a disaster, plus it was working fine until very recently).

EDIT:  And just like that, 20 minutes later... Skype started making noise again.  I have absolutely NO idea why... I didn't do a thing.

EDIT 2:  For whatever it's worth, Skype stopped making sounds again a couple days later.  Then started again.  It seems to basically just be random... sometimes it will make sounds, sometimes it won't.  No rhyme or reason!
Please check if you are in do not disturb mode as it affects it. Look for the moon symbol in the notification area.
