Hi all!
I have released an update of my app on the 22nd of January and Google charges me 0.11 EUR per day since that day for Google Cloud Functions within the app's Firebase project. The detailed descriptions are "Idle Min-Instance CPU Allocation Time (tier 2)" and "Idle Min-Instance Memory Allocation Time (tier 2)". I know it's not much but I'd still like to know where it's coming from.
I use Firebase in this project only for user auth incl. Firestore users collection (currently having 57 users), analytics and since 22nd of January for Performance Monitoring. No storage, nothing else. I did not have any cost before that day. Could it be that Performance Monitoring is the reason for these charges? I did not make any other modifications related to the Firebase project.
Thank you!
