So the issue is only on Mobile. If you use the search glass within the search bar everything works fine
If you use the search/done button from the keyboard, isn't working.
Thanks for reaching out.
I appreciate the context that you have shared as well as your online store URL. Could you let us know which theme you are using? As this will determine the next steps to troubleshooting the search function on the mobile version of the theme in question.
Looking forward to your reply
