I use filters to classify several high-traffic mailing lists. Incoming mails are tagged with the appropriate label and do not appear in my Inbox. Thus I can review them at leisure without having to deal with each message as it arrives.
Which is kind of the whole point of filters.
This has worked perfectly for several years, but recently the "Skip Inbox" part of these filters has stopped working. Although the messages are correctly tagged, they all appear in my Inbox. I thus have to select them all and manually archive them to get the behaviour I want. This is especially difficult to do on an Android phone (nb: the Android Gmail app has no "select all" feature). I've careful reviewed the filters and can see nothing wrong. BTW I'm using "list:" as the matching criterion for these lists.
I suspect this problem arose when the new Inbox tab feature appeared, but I can't be sure. Currently I have these messages classified as Forum and that pretty much works, but I still have to do the manual archiving, which frankly sucks. Note that the problem already existed *before* I actually set up the tabs thing, so it may be purely coincidence.
I also have a Google Apps for Education account, with a similar setup (for a different set of mailing lists) and it still works perfectly.
