Iäm having issues with sending daily notifications on android. I feel like i have tried everything. The code below is what i use, and then i initialise init in main.dart.
I see no errors, i see correct logs for the scheduling calculations (as shown at the bottom), but the notification never comes. I also pasted the uses-permissions i have in androidmanifest. Any help would be grealty appreciated.
TheinstantDebugNotification function works perfectly, its just the scheduling notifications that doesnt work
