I think we are now transitioning to Simple File List plugin (https://simplefilelist.com/)
Noting also that we have no connection — financial or otherwise — with above WordPress plugin just passing this info along in case helpful for other organizations.
Well, we upgraded to WP 5.8 without any hiccups in FileAway.
It is remarkably well written to have lasted this long without updates.
And such a great plugin of benefit to so many.
Sure hope some support might resume.
