OTA updates not happening and not covered out of warranty.

Took my P2 in yesterday for an MOT had asked that they check the app connectivity as it had not been working.

Went to look and it froze the tech checked the software version and said its out of date by 3 versions. There is no way to update it from the car now it needs to go back in for service.

He also mentioned that it won't cost anything this time as the car is still in warranty however if it wasn't it would be chargeable.

It seems strange to me that if an update is skipped (not that I was aware it had been) you can't force the updates to take place, is this everyone else experience?

It also seems that this being what seems like a flaw to me that it should be chargeable if out of warranty, or am I crazy?
