Worst experience ever on IOS update (IOS 14.0.1)

I am having such a terrible experience on IOS14.0.1

1) Bluetooth connection

while i use my airpods pro to listen youtube, or other apps, it keeps disconnecting and reconnecting, sometimes it disconnects straight after it reconnected, sometimes it would last for a while, it really depends...

I've already reset my phone setting and even restored my iphone, issue remains the same, i'm so sick of it

2) this morning my alarms were not working and i was nearly late for my work

3) speaker was not working after updating to IOS 14.0., it seemed to be working fine now, besides the alarm wasnt working this morning

4) issue occurs after setting face ID, bluetooth issue may cause by that

5) my credit card cannot be added onto my iPhone wallet

IOS 14.0.1 is surely a nightmare to me. so Apple please fix it ASAP!!!!!
