It’s not on the bugslist, because it’s not a bug.
It’s clearly related to the used chargers/cables so an easy fix is to get a charger from the list and a good USB-data (4 threaded)-cable.
It is on the commonissues though.
I don’t think it’s a good idea to create a support ticket, because support won’t give you any different answer than to use a different charger/cable.
I don’t see any relevant difference to the FP2 unusable while charging thread, so I’ll close this topic. Please continue over there if you want to discuss further.
