Fix: File Previews Were Blank and Training Uploads Failed

Details

A file you attached in chat or opened from Drive showed an empty grey box instead of the document, even though your employee could read it perfectly well. Uploading a file on the Training page failed outright with an unhelpful error. Both are fixed: previews render again everywhere a file appears, and training files upload and start learning as they should. If an upload does fail now, the message tells you what went wrong instead of leaving you guessing.

What changed

• See PDFs, documents and spreadsheets preview in chat and Drive again
• Upload files on the Training page and have them go through
• Get a clear reason when an upload cannot be accepted
• Files up to 72 MB each, the size we can actually deliver
