Hi Administrator Kommunikation! Thanks for reporting — that sounds super annoying, of course. So that we can narrow it down more quickly: What exactly happens during the upload (error message, endless loading or does the upload not start at all)? Does it affect all files or only specific file types/sizes? And where exactly does it occur (e.g. in an email campaign, in a form/landing page, or directly in the general file manager/asset area)?
