Thank You very much for this plugin, searched for a few hours for the solution. Could You kindly look into CPT support for these notifications? It works only for posts now.
Also – when someone replies to a comment of the author on the authors post, the author receives two notifications simultaneously:
XY commented on one of your updates 4 SECONDS AGO
XY replied to one of your activity comments 4 SECONDS AGO
It is kinda weird, maybe have the notification only for the first level comments?
Thanks for responding.
