iTunes Radio lagging/buffering a lot after update to 8.2

I'm wondering if this is a Bluetooth issue...

After updating to iOS 8.2, I have noticed whenever I have more than two Bluetooth devices connected at a time, the audio (whether it is coming from iTunes Radio or the Music app) stutters really bad. I've had the same setup for the past year - I have the Bluetooth connected to my car (for phone calls), connected to a Bluetooth music receiver - so I can listen to my iPhone's audio through my car's speakers, and then my Pebble watch (to be eagerly replaced with an Apple Watch next month) is also connected. I have NEVER had music pausing problems before the 8.2 update, but it is constant and unlistenable since the update. There is no doubt it is tied to the update. If I disconnect the Pebble bluetooth connection, it's fine, or if I disconnect my car bluetooth, it's fine. But all of them connected, it doesn't play smoothly, at all...

I've noticed the same as LB Jeffries. If 2 Bluetooth devices connected, I can listen to music through Bluetooth. If 3 Bluetooth devices connected, the music plays in Bluetooth but it shutters a lot. Every few seconds it shutters. Disconnect one device (to bring it back to 2) and music plays OK. I've tried connecting and disconnecting the 3rd device many times and same result. I've also tried the Reset All Settings and Reset Network Settings with no improved result.

I used to have 3 devices connected all the time and it worked fine until 8.1.3. I got this issue after the upgrade to iOS 8.2. The 3 devices connected are a Bluetooth OBDII reader, car phone and USB dongle connected to car radio.

After weeks of reading about iOS 8.2 issues (and finding only seemingly very minor stuff or isolated cases), I thought it was finally safe to risk another iOS update to fix my long-standing Bluetooth issue. Ever since iOS 8.0.x, we have been having the very annoying BT issue of call audio cutting in & out when connected (and it may be that the iPhone/iPad actually randomly disconnects and reconnect with the car's BT every 10-120 seconds but we just don't notice it without an active call).

So after reading about how 8 iOS 8.2 is supposed to contain a BT fix, and the apparent lack of serious BT issues (or so we thought), today we updated all our devices to iOS 8.2. What we found was almost as disappointing as iOS 8.0.2 for us.

I won't comment on whether iOS 8.2 finally fixed our existing BT issue, as that needs extended testing for several days at least for a preliminary result. However, we immediately noticed that IOS 8.2 ADDED A NEW BLUETOOTH PROBLEM to the mix! With iOS 8.1.3, we could stream audio (I.e. Pandora) at higher quality perfectly. Right after the iOS 8.2 update, everyone suddenly noticed that the audio from Pandora or other streaming music app would briefly pause or skipped and stuttered every few seconds. We could be streaming only at "good" quality instead of "Better" or "Best" but that would not make a difference ("good" is around 64 kbps). At any rate, you would think that a 6.8Mbps 4g connection would be enough to stream a 64kbps signal without stuttering/buffering.

I hope Apple is going to fix this issue in iOS 8.3 or sooner... more and more people seem to have this (or variations) issue, and many others also are affected, probably haven't noticed (yet).

UPDATE 4/2/15: Tonight I tried to stream Bluetooth audio from Pandora and Rhapsody through my UE Boom. I had my Pebble Steel, Panasonic 6.0 DECT Link-to-Cell Cordless Phone System, and UE Boom connected via Bluetooth at the time. Bluetooth audio skipped 1-2 times per second. This issue is getting very frustrating... to the point where I want to throw my iPhone in the trash.
