Trello just says "unable to upload file" and nothing more. This is happening with all the cards I checked. Any ideas?
@Vinicius Spira Are you on a free plan trying to upload a file large than 10MB?
I have the same problem trying to upload a 30KB image. This gets logged into the browser console:
[Error] Failed to load resource: The operation couldn’t be completed. Protocol error
…but no details. Current Safari on macOS Catalina.
