Similar story here. Put in my 14 day availability for the initial 90-day window. Check on subsequent days and showed expired then happened to see that at some point after I had been expired for several days I was magically back to normal and the extension applied. No word or warning about it and certainly no question asking if I was ok with it.

CPO says that it's being looked at as all pilots are extended since the FAA allows it even though that is NOT what was stated in multiple flight ops updates. I too missed a second window of putting in 14 days but according to my rep that isn't required to do a second time anyway. CPO disagrees, of course. I was also threatened with no pay as well for proactively requesting a sim ride to get up to speed.
