Hello!
I’m sorry to hear that you are experiencing issues with the import process. There could be a few different reasons why the import is pausing after reaching 100%.
One possible cause is that your hosting environment has resource limits that are preventing the import from completing. You mentioned that you increased the file upload size and extended the execution time, but there may be other limits in place such as memory or CPU usage that are causing the import to pause. In this case, you may need to contact your hosting provider for assistance in increasing these limits or troubleshooting the issue.
Another possibility is that there is a problem with the export file itself, such as a corruption or a missing element that is causing the import to fail. In this case, you may need to regenerate the export file and try the import again.
I hope this helps. Let me know if you have any other questions or concerns.
