Right pedal dead after battery change

I have run my pedals with CR1/3N batteries for 6 months without issues. The low power warning just came on so I changed batteries. First I put LR44's in I had laying around but had massive drop outs on that ride. Put in CR1/3N and the right pedal won't wake up. Changed back to LR44 but still dead. Tried cleaning the contact surfaces.

I get a 0 error code and after a few tries 1024. Funny thing I got a successful calibration while pedaling on the trainer!? But then back to 0/1024.

I've asked support for new pedals but just wanted to know if you had any last tips? Hawaii coming up in 4 weeks...

Posted on social and got lot's of "Happened to me too...". I know at least 4 people having non working Vector 3's right now.
