What glitches have you found in Android O Beta thus far?

[AC Question]

My Nexus 6P (on Google Fi) recently received the OTA for Android O, along with an update last week. Thus far I'm happy to report very few bugs, and even those are more of the "annoying" versus "crippling" variety. What I wanted to do was form a running list of bugs encountered by users so we can get a full picture of this Beta. Post away!

* Please only list real bugs or glitches, and/or known fixes if applicable. I want to avoid this turning into a complaints forum. We're only in Beta after all. Thank you!
