This is a strange one that I don’t know I can even demonstrate reliably. When I am in the file browser and a select a file to edit (this could also be in job composer, or any place where files can be edited), very quickly a page that says Failed to load file pops up which is immediately replaced by the file editor.
I think the page says File failed to load. Please try again later.
Is there a timeout set somewhere that’s really short?
@groucho64738 What was the file extension of the file you were trying to open? We’re aware of a few bugs in the Files App with MIME type mismatches that could be the cause of this.
