Special characters within the Zoom phone comments in Salesforce

Hey, 

It seems that we are unable to use certain special characters within the comments field of the Zoom phone integration with Salesforce. 

When trying to add either '#' or '&' to the comments box, the following error is returned. "Unexpected end-of-input: was expecting closing quote for a string value at [line:1, column:265]"

We have the field synced to a long text area in our task object. 

Can anyone please advise? Thanks
