Anyone else experiencing this issue?

Sometimes it works, sometimes it doesn't. Sometimes it goes to vibrate once the appointment starts, sometimes at a later time (no consistency) and sometimes not at all.

Getting irritated looks from co-workers during meetings so I'm about ready to bag TFL3 and go back to SPB suite.

Just turn it down manually? I know it is frustrating as it is supposed to do it automatically, but just hit volume down 1 time, then touch vibrate - done.

This working for me consistantly. Not certain why it is not working for you. I too prefer it to be automatic. I would forget frequently if was not on Automatic.

This happens to me all the time! I'll be sitting in class and the phone starts ringing. As far as I can tell, it seems to be completely random. I have several classes back to back, but I have them entered as seperate appointments so I can delete one if a class is canceled. It doesn't seem to have any rhyme or reason to the time that it goes off of vibrate mode (or never enters it in the first place).

For a couple days, it decided to vibrate while [i]not[i] in appointments.

The only fix I have found is to do a soft reset. This resolves the issue about 80% of the time.
