we recently updated to Moodle 3.5.2 and updated this plugin to the latest version (3.5.3) which should be compatible. For the MORE theme, in the Attendance Report page the table of users split between the user names and the emails, just like shown in the image attached. This doesn't seem to be caused by our core code or custom css (we removed css customizations and it's still happening). I am guessing this might happen with Clean as well, but have only tested it on More (which is the theme our Moodle is using). I applied a css fix for now, but that is a short term solution and it can meddle with other sites of Moodle as well.
Thanks in advance!
