Hmm... So I see you can deactivate the confirmation on the mark all as read.. Apologies to the developer, criticism on that point rescinded. 🙂 But the issue of marking things as read as you scroll still is there, is there something I'm missing? I'll scroll through a whole feed and not see the count change.
Tap the gear icon up top to access the feed settings where you can turn this on. I really need to add a help graphic to guide people to the features.
