they definitely have, they only work when I unlock my phone, and then they pop up all at once. they don't go to the lockscreen. this is by far the worst beta experience I've ever had, I'm not joining another one. 4 months on a beta program is ridiculous. next time, I won't be signing up for it. it's not been worth it at all. it's been absolutely hell, the battery running low, the over heating of the phone, the notifications, apps not running properly, lagging, camera problems, notifications on apps not going away, I could go on. it's been awful. lesson learned for next time.
