Following the change to 'App Engine max_idle_instances setting will apply per-version starting May 24, 2022
', I have migrated all traffic to a single version and removed 3 other versions.
My settings are (for all current and deleted versions):
min_idle_instances = 1
max_idle_instances = 1
The Console's Instances Count show a normal behavior.
However, hours are counted and billed as if there are some 4 extra instances running at all times.
I have disabled and re-enables the application.
When disabled, no hours are counted. When re-enabled, the same issue persists.
I cannot easily re-deploy, as I will have to catch up with all changes of the past 2 years.
Thanks in advance
