Airpods Pro stuck on flashing orange / red light - no Connection SOLVED

Currently going through this now, after some failed attempts. But finally i managed to get BOTH to finally connect, so finally I have two different BT entries, so i can proceed.

My replacement left airpod pro is on firmware 2D15

My original right airpod is on firmware 2B588

Does anyone happen to know which is the latest ? i'm assuming the right, as that is the original, so not been sitting in a warehouse with an older firmware.

The reason i ask is cos earlier today i couldn't get the right to connect, no matter how many tries, so i called Apple and they're sending me a new right airpod. I also have an appointment with at the store on Tues. I'm guessing the R that's coming will also be on 2D15... ugh, meaning if i want the newer battery, then i'll have to go through this entire rigmarole again.
