How to reset the theme?

Recently, I’ve encountered more caching issues. After modifying the config and styles in the theme editor and saving them, no matter how many times I refresh the frontend page, I keep seeing the cached old version. This problem occurs sporadically. I previously reported an app metafield caching issue, but this doesn’t seem to be limited to app metafield caching alone. It appears the edge node cached the page and failed to refresh it promptly.
