It may be that the current entry only supports text or specified type transmission. Clipboard and file upload are different functions.

Android apps may also only accept import via the file picker, and direct pasting will not trigger.
A practical example
Hypothetical example: Text can be pasted in, but pictures or installation packages cannot. This does not mean that the entire connection is abnormal.
What to check or try
- View client file functionality.
