The slow or non-existent notifications is one thing (especially with a handful of articles submitted to publications, so I have to physically click on each article to see if tweaks are needed), but it seems to also be causing problems with the read stats, which is affecting pay.

Notification problems is one thing, but problems that affect my income, that's another (and the lack of any updates from Medium, other than a banner on the help page, is a bit troubling).
