Cannot upload a file

Check the upload

1. Confirm you can create or update files in the project.
2. Check the file opens locally and uses a supported format.
3. Shorten an unusually long file name and remove unsupported characters.
4. Retry on a stable connection, then refresh the Files or Drawings page.
