An issue commonly encountered when integrating Progressier into your Shopify store arises from a prior installation of another PWA plugin that was not properly uninstalled from your store.

The solution is fairly simple. Remove this line of code from your store's theme:

Each PWA can only have a single web app manifest. Web browsers will use the first manifest they encounter in the code, regardless of its validity. Unfortunately, there is no method to replace an existing manifest with another.

In other words, if you neglect to remove this line from your code, the browser will utilize an invalid manifest instead of the accurate one that Progressier would generate for you.
