Hello,
I have replicated this issue on our test setup and find that it works fine.
This could be a third party plugin which is causing code conflicts.
- Please deactivate all installed 3rd party plugins.
- Delete browsers cache if installed.
- Re-save permalinks.
If it does not work only then share your course url, wp-admin url and credentials in a private reply so that i can look into this matter.
also let me know if you are using an iphone to test this issue.??
