Notifications aren't working for you? They're working just fine for me. It's categorizations have been kind of odd, but after a day of fixing that manually, it seems to have figured it out.
What'd you do to fix it manually? Unless that's in the article, in which case, never mind, haha. But yeah, notifications are busted. Reinstalled, installed, sent google a help ticket and waitin on a response. Speaking of Notifications, mk, this may just be a personal browser issue, but notifications in Safari are frozen. They work just fine in Chrome, though, and the rest of Hubski works in Safari. Just notifications. Weird.
The sorting? I just hit the three-dot thing on the right, and for "bundled in" I change where it gets bundled into. Seemed to do the trick for me. Keep in mind, I do that on the web interface, though it seems consistent to the iOS app as well. My one issue is how it handles "pinned" e-mails. I want these to be liked starred e-mails in Airmail - ever present. I keep sentimental e-mails or important information there. In inbox, if you snooze or finish something, the pinned e-mail goes away ( :( ).
