HTTPS page contains internal links to HTTP

Question:
Is there a way to solve the issue “Https poge contains internal links to Http”?

Product:
Wix Studio

What are you trying to achieve:
I am performing Site Audits for my wix studio website on different platforms (e.g. Ahrefs, Yandex, etc.)
I keep getting this error, which is marked as “critical importance”:
HTTPS page contains internal links to HTTP

There is no clear explanation on how this issue originates, and I suspect it has to do with the internal workings of Wix.
From my understanding, Wix automatically includes a 301 redirect within the code which sends all http requests for the website’s domain to the correct https counterpart.

Example:
If you type http://www.mywebsite.com into the search bar, this safeguard automatically redirects you to https://ww.mywebsite.com

However, this code seems to be stored within the html of the page, even when the https protocol is being used. This causes this pesky error to show up in site audits.

Is there a current workaround?
Does this large number of 301 redirects negatively affect SEO?
Have you experienced the same issue in the past?

What have you already tried:
I have tried inspecting the live websites to pinpoint the origin of this issue, with no result.
The redirect manager in the Wix Dashboard also does not contain the solution.

Additional information:
I have encountered this issue after building a website with Wix Studio. I did not experience this issue when publishing a website using the “standard” Wix Editor.

Can you share the links that are showing up as HTTP instead of HTTPS?
