I have the issue, that in my Customer Insights - Journeys installation, the upload button is missing in the media upload interface (see screenshot).
I have already created two environments and in both this bug persits.
The Support is not really helpful since their answer was (no joke) /try to fix the bug/ ....
I tried in every single submenu to upload an image but failed to do so, because the /Upload/ button is always missing.
The system admin is also not able to upload images.
The Version is: 1.1.37290.68
We have also outbound marketing installed (since obligated to have double-opt-in), the version is: 1.101.2010.0
