No technical issues booking FastPasses this morning here... but the only things I booked when my booking window opened at 6:00 (CT) were Navi River Journey and Flight of Passage; I didn't book the rest until about 9am.
Didn't really have any trouble getting the FastPasses I wanted, aside from Slinky Dog Dash-- my Hollywood Studios day (well, half-day) is the first full day of my trip (9/9) and SDD was already all gone for the day when the booking window opened today. Hopefully I'll be able to get it during morning EMH that day, but, TBH, I won't be that crushed if I don't (I'm kind of underwhelmed by Toy Story Land in general).
Schedule and my planning spreadsheet so far (which I'm pretty proud of) are attached:
