Jeez, we know they submitted an update. It included the subs button and the important bugfix. It got rejected. We know that, and we know why it got rejected - the subs button. Its a clear breach of the rules.
What all the articles are now fumbling is the issue of whether MS RESUBMITTED the app with the subs button removed. The article writers wish us to believe yes, and that Apple scandalously rejected it, but they're not saying it. All they have said is that MS have offered to remove the button. Offered.
The most sensible interpretation is that MS are trying to get the original update approved, despite the subs button, because it fixes the bug. They are offering to remove the subs button on the next update in the hope that appeases Apple. It has not. Apple have refused to pass the update, and require MS to resubmit it with the subs button removed.
Yes, it's a bit of reading between the lines, but it makes a hell of a lot more sense than what the article writers are trying to coax us towards believing.
Wait and see. MS will resubmit within a day or two. Crisis over.
