@jleyva as discussed in issue #241

enclosed you find our merge request for M4.1 - below you find the changes and to do's
It's been tested by various community members, and I have not received any input that makes me think it breaks things.

It would be great for the community if you can review the code and when you agree push this version to Moodle.org plugin database.

As said - we will not continue maintaining the plugin. If issues appear we suggest that people from the community send in their own fixes. or contact us to fix this for them against a fee.
