I know it's a little late but I just noticed that since July I've been getting billed around $90 a month for compute but I actually don't have any active projects running on Neon, so I have no idea how my bills during this period could be so high?
For development I don't even use Neon so I need to see some logs or something to justify this or get a refund for all of these months.
I didn't notice it until because I kind of spend indiscriminately without looking, and just checked into my Neon to check up on my account.
