Search feature not working

For the past month or so, whenever I type a prompt into the search bar, it says there are no results. I've been using Express for years (since Spark, etc.) and I have never had this issue. For example, when searching for a social media post or template for Valentine's Day, I type in "valentine" and there are zero results. In some cases, it will bring up something I created in the past, but nothing from templates. This doesn't make sense to me because when I browse some recent templates, there are several Valentine's Day templates that come up immediately. The best part about Express is being able to search for a template based on a key word and remixing that design to save time and resources. Now, I try to search any number of things (MLK, ocean, cupcakes, invitation, literally any word) and there are no results. Please help! Thank you!
