After upgrading to WordPress 5.5 then 5.5.1 there were issues with the Polestar theme meeting the revised core coding with respect to deprecated or dated code in the theme and possibly plugins.
Running the jQuery Migrate Helper plugin developed by the WordPress Team to temporarily resolve issues. When errors are reported by this plugin, it was recommended that the theme user report these errors to the theme developer to ask if a THEME UPDATE can be produced to resolve these errors.
Has anyone else using the POLESTAR encountered issues using this them with WordPress 5.5.x???
Need review and advice.
Thanks, Richard
