A Shopify store owner uninstalled the SEO Booster app but discovered leftover code preventing metadata updates. The app had modified the theme’s meta title and description tags in the theme.liquid file.
Proposed Solutions:
Version Rollback: Check theme editor’s “Older versions” to restore a pre-installation backup. Use diff-checking tools like diffchecker.com to compare versions before reverting.
Manual Code Removal: Delete SEO Booster-related files from the SNIPPETS folder in the Shopify code editor (confirmed working by one user).
Code Replacement: Access theme.liquid via Online Store > Themes > Edit code. Compare current code with the “Original” version under “Recent changes” to identify modified meta tags. Replace the app’s code with the original meta title/description markup.
Status: Multiple users report the same issue. One confirmed successful resolution by deleting snippet files. The discussion remains open with working solutions provided but no confirmation from the original poster.
I have uninstalled an app i.e. “SEO Booster app” from my Shopify store. But, I should remove its code from my Shopify theme as well but don’t really know-how. If somebody knows then let me know as it hinders my overall SEO as I am unable to update the metadata.
Regards,
Samantha

Likely this is something in the theme.liquid file. Have a look at Older versions when in the theme editor, if you can find a version before the install can probably roll back to that, assuming there are no other customizations you would be undoing or breaking.
Sometimes I use a diff check tool like https://www.diffchecker.com/ to highlight what has changed between the current and version you are thinking of rolling back to, to be safe.
Is your theme paid? Maybe you could ask the theme dev to help.
Otherwise if that is still too hard, you’d probably need to look at getting some help from an expert or on Upwork or something.
Did you manage to make the changes? I have the same issue.
I had the same issue. You can find those pieces of code on the Shopify code editor, under the SNIPPETS folder as shown below. You can simply delete these files and problem solved. 
After checking your question, it seems like SEO Booster APP has changed your original meta title and description contents and replaced with their own ones. If you need to clear or revert the code, you can use the following ways I shared below to get some help.
