My app does not load on Safari

My app works fine in Chrome and Firefox, but in Safari, the app just does not load. I can see this error in console: 

[blocked] The page at about:blank was not allowed to display insecure content from http://<my-app-link>.

I don't know why it's loading with http when the links in app setup are all https links. 

There are no mixed content either, to test that I even simply just rendered a blank html with the text 'hello', still getting same error.

is your website hosted in Shopify or a custom domain? If you are using a custom domain make sure that it's redirected to your Shopify store properly.

I am testing the app I developed in a development store. It does not have a custom domain.

Using Localhost? I do believe it's an HSTS issue.

No, actually localhost works fine. The issue is only with the staging and live apps which are hosted on real domains.
