I upgraded to v2.7.0 and noticed that the document upload is not working anymore.
When I upload a png, I get the checkmark that it succeeded. But if I than save the invoice or quote and go back to the documents tab, the thumbnail is broken and when I click on it I get “Whoops, looks like something went wrong.”
If you need further details, I’m happy to provide them.
Extra note: when you drag&drop multiple files (PNG in my case), at least 1 file will fail and sometimes need to delete and re-upload. Also experienced this in the previous version.
