Ok
1 . we are not able to face any such issue at our end .Can you please create a staging or copy of your site so that we can check this there .
2 . Please check if student login redirect is set from wp-admin -> lms -> settings .
3 . This was always coded to show all description there in the course page in profile , we have not changed anything.
4 . This is also needed to be checked on your site .I guess the issues is due to old cached js and css files .
Please delete all kinds of cache after update and deactivate the cache plugin for some time (1 hour min) and then check these issues .
