Delayed notification on Desktop clients?

Hello, Iā€™m not sure I should post a bug report so I figured I should ask here first ?

When sending a notification to a user (ex : ā€˜sudo nextcloud.occ notification:generate refhi test testā€™) I get an instant notification on my phone (max 3 seconds on Nextcloud app on Android), but itā€™s delayed on the web interface (around 10 sec) and extremely delayed on the desktop client (hours sometime, unless I manually check the notification).

Iā€™m on a fully updated snap nextcloud server and my clients are up to date. Iā€™ve had this problem since the begining (3 years ?).

I googled a bit, looked on github for other people talking about it but couldā€™nt find anything substantial. Does anyone else have that kind of problem ?

(Iā€™ve poked around notify_push without success)

Thanks !

all kinds of clients should poll every few seconds (15,30,60 donā€™t know exactly)ā€¦ until you install notify_push: this must turn notification into almost instant. if you need help with notify_push check this post

for other issues try to isolate the problem and report exact problems with corresponding logsā€¦
