RefWorks has now released its support of APA 7th Edition, which was published in October.
Update December 17, 2019: DOIs should have ONLY the DOI itself in the data field - the style will add the https://doi.org/ for you. It won't strip out anything so you need to remove it if you've added it.
Also it will not adjust title case for you so you need to do this yourself in your citation records.
This is the equivalent of the "APA 6th (No title casing applied)" option - RefWorks does not currently plan to offer a 7th edition style that adjusts title casing.
