I noticed submitting bug-reports with 2018.1 seems to take longer than with earlier Unity versions. Especially empty projects, that just contain a script and text file, were submitted in like 3 seconds in the past.
With 2018.1.0b7, it takes almost a minute to submit an empty project here and I can see the “Uploading bug-report” progress slowly increasing, which normally went from 0 to 100% in no time with earlier Unity versions.
I wonder, is 2018.1 submitting hidden/additional files now? Perhaps packages that are not part of the project directory itself?
