Hi,
hours, felt days later trying every possible combination of settings, I am at the end of my limited wisdom :-(
Both my devices, a Sony Z3 tablet compact and a Samsung S5 duos, both with the last possible Android version 6.0.1. show the same error-pattern:
About 2, maybe 3 months ago everything was perfect and then both failed to work at the same time, I am quite sure.
Now, there is no more LED- sound- or vibrating-notification of incoming mails any more.
Only with priority-notifications from selected mail-adresses there is the chosen sound and vibrating, but no LED too.
I know, that I have once switched off the Priority-notifications at both devices, when I needed silence. 1 week later switched them on again.
Not sure, if this error-pattern developed when doing this, maybe.
Checked of course every possible setting from both phones, which are a little different, Samsung shows the menues very differently. But all permissions for the app seem to be activated.
Please bear with me, if I have overseen a problem-solution within this forum...
Thank you, Thomas
