After the online industrial and commercial change materials are submitted, they return to the status to display their signatures, which may be due to the following reasons:

1. The signature is incorrect.

2. The signature picture is not clear.

3. ID card information has not been uploaded or expired.

4. The submitted documents are inconsistent with the actual situation.

5. The network is unstable.

In this case, I suggest you check whether your signature is correct and whether your handwriting is clear, and ensure that the information on your ID card and other related documents is correct and meets the requirements, and the network environment should be stable. If you don't have the above problems, you can contact the relevant departments for consultation.
