Hi KlishBrian,
Thanks for your posting on Q&A.
Should I leave both versions approved?
No. There is no need to do that. As you mentioned above, the clients have downloaded the November released 20h2 feature updates. In my opinion, there is no essential difference of the feature updates between in October、November and December. The only difference is the cumulative updates included in the update package.
I found the following picture to share with you:
We may need to install cumulative updates on the clients after upgrading to 20h2 successfully. Please try to install the latest cumulative updates(kb5001649) to upgrade to latest(19042.870).
Hope the above will be helpful.
Regards,
Rita
