Sharepoint URL converted when accessing from PowerApps custom form

Hello,

I created a sharepoint list with Sharepoint URL inside of it.

The content of this Sharepoint list is then displayed in PowerApps custom form.

Once users are in PowerApps and they click on this Sharepoint URL,

the URL is modified from "https://my-domain.sharepoint.com/sites/..." (where my-domain represents the name of my company)

to "https://content.powerapps.com/sites/..." automatically,

resulting to an Error 404.

I have this issue only with Sharepoint Site URL.

I put a URL of another site and it's working fine.(e.g.  www.google.co.jp)

Why Sharepoint Site URL is converted?

How to avoid that?

Best Regards,

Kuranoo
