Hi, any chance of checking ownership, cos apparently I own the PI as well, and am paying upkeep. so from what you've said, we both own the same PI, and we both pay upkeep. which would look like a bug.
if it helps I am the original and current owner of the PI, and Ji should not be paying upkeep.
Would you be able to dig further into the Upkeep issue? for instance are you able to find the deductions from Ji's account, and see what they are due to?
