We have just upgraded our Moodle site to 3.7 and have face to face plugin version 3.4.3 (2018110900).
Previously students had the option to cancel their booking, but now this is not available even when we tick the allow sign-up cancellations default in the edit resource section.
Have also noticed that in the edit session section when we tick the allow signup cancellations it does not hold the choice on save
and finally, we can no longer enter a sign-up close date, we had the option previously to do this as well.
Any help or insight would be greatly appreciated as at this stage the plugin as it is working is no longer useful for our organisation and I haven't been able to locate a suitable replacement.
