I had enough of the dropouts on 9.40, and the mid-ride restarts of 9.50.
Reverting back to 9.10 has made my 530 usable again.
What does 9.60 have in store?!

Did you have to reset / redo the settings in the Edge after you downgraded to 9.10? I'm also slowly getting to the boiling point of having sensors dropout. Luckily haven't got the restarts (yet), but don't want to push my luck.
