Step by step
- Capture the full message and enough of the screen to show which field it refers to. Cover passwords, codes and personal details that are not needed.
- Add the screenshot to Sense Bridge and ask for an explanation in English. Compare the file name and size limit with what is on the screen.
- Retry with a suitable file. Check that the attachment appears and look for a submission confirmation. An attachment error alone does not tell you whether the rest of the form was saved.
