Ins could not refresh the dynamic.

The program cannot refresh the dynamic for the following reasons:

1. Check whether the network connection is normal. If there is nothing wrong with the network, the Instagram server may be out of order. You can change the network or try again later.

2. There may be problems with the 2.Instagram application itself. You can try to reopen the Instagram app, or clear the Instagram cache and restart the app.

3. Make sure the Instagram application is the latest version. There may be compatibility problems with the old version. You can go to the app store to see if there are any updates.

4. If the storage space of the device is insufficient, Instagram may not be able to refresh the dynamic. You can try to clean up some content to free up storage space.
