Another observation after updating to WP 5.5:

I cannot enable auto-updates for all plugins. For example, Restrict Content Pro, BBQ Pro, Blackhole Pro, Newspack Blocks, WP Retina 2x Pro, and some extensions to the main plugins will not allow Auto Updates.

After enabling updates for all plugins; 26 plugins are now enabled for Auto Updates while 17 plugins are not enabled and can’t be enabled.

Am curious if anyone else experienced this behavior when enabling Auto Updates for plugins?
