I got an email saying network transfer for the free plan was used up, but I only have a test db of 0.06Gb that I use only some days to test things out (no app/data connection exists outside of tests), but it has now reached 5.17GB network transfer on its own apparently, without me using it for several days now.
Network transfer is defined as: The total data transferred in and out of Neon across all projects in the current billing period
How has it got used up when the last time I used the db several days ago, it was well below the limit?
