Plugin Updates Not Showing After 12.1.1 Update

I work for an agency that works on over 800 sites, and after the 12.1.1 security update, several sites are no longer showing updates. Is there something that would prevent updates from showing? Some of the sites are connected to WordPress.com; some are not… I can’t really track down what is common between all of the sites that is different than sites that sites that are updating okay.

Everything under the Jetpack tab for Site Health matches the sites that are able to be updated, and the connection test says “All Pass.”

I can send more site links if needed, I just didn’t want to post them all here as they are clients. Thanks!
