Since it doesn't look like you can post comments attached to the announcement of the new app, and I don't see any discussions about it anywhere else, I'm putting it here, since this seems like the most logical forum. If one already exists somewhere, please feel free to merge or move this one.
So far, I like the app (iPhone version), but am wondering if there is a way to show which threads have new posts since my last login. I use this feature all the time on the website & don't see myself using the app if there isn't a way to highlight new threads.
To answer my own question, apparently there is a way to show this. I must have changed a setting or something because now a blue dot is showing on any newer threads. Not sure what setting I changed, but just in case someone else searches for this issue, it is possible.
