Hi metdown, so on your iPhone the notifications work just fine when using Safari, but when using Chrome mobile browser, they don't?
Hmm did you also add the site from Chrome to your home screen (that it essentially shows up as it's own app) as shown in this guide?
https://forums.d2jsp.org/info.php?p=92If everything else fails, you could just go ahead and have your notifications be pushed through by Safari, and upon receiving it then open your browser of choice. It shouldn't make too big of a difference because you are still notified upon getting replies in tracked topics or PM's.
