Some form quries are not sent to google sheet file

I set the plugin up and everything seemed to be working, but then I noticed that some of the entries were missing from the drive file.

I didn’t see any errors in plugins log file, so I added some of my own logging lines to the plugin. It seems that google sheet service throws quota exceeded error sometimes, I guess because the connected API service account is used on all plugin instances.

Is this a excepted way it is supposed to work on the free plugin?
