I’ve been thinking about this a lot as I test the new Discourse Chat plugin. The chat in itself makes me much more excited to use Discourse with a group and yet, iOS not allowing progressive web apps (PWAs, or when one clicks “Add to Home Screen” from Safari) to send notifications makes it hard for mobile usage. I mean, for me, I may see it as a blessing, as I often turn off notifications anyway, yet not sure community members would agree.
Apparently PWAs can have notifications on Android, so it seems to be just a waiting game until Apple allows them.
In the meantime, I don’t know what the other options are. DiscourseHub seems to give notifications only for Discourse-hosted sites, and Fig for iOS, which I like, I think has stopped being developed.
