I noticed you’re not bumping the plugin version number when you make updates. As a result, the plugin never ask to be updated in the WP dashboard (there is no automatic updates neither).
You absolutely need to bump the version number metadata (in the readme.txt file): https://developer.projectdmc.org/plugins/wordpress-org/how-your-readme-txt-works/#field-details
I’ve a client’s website where the version is officially the same, but is in fact from January 2021. Hopefully there will be no breaking changes.
