And this is from Marriott:

We are focused on how the coronavirus is impacting our Marriott Bonvoy Members and have made some important updates to our loyalty program to provide greater flexibility when planning future travel. Specifically, we have paused points expiration until August 31, 2020 allowing Members ample time to redeem their points. In addition, we have extended the expiration of suite night awards (SNAs) with an expiration date of December 31, 2020 by one year to December 31, 2021. Lastly, Members who currently have an active Free Night Award (FNA) expiring in 2020 as part of their credit card benefit, annual choice benefit, promotions or travel package will be able to use it through January 31, 2021. We understand that earning status for 2021 may also be on your mind. As the current situation is still evolving, it is too early for us to make any changes. We will keep you updated on all loyalty program changes through our Marriott Bonvoy member benefits
