When you click on the View button on published posts is bringing the preview link (ending with ?preview=true) instead of the correct link to the blog post.

Expected behavior

The actual link to the published post. In my case, https://eduardoistesting.blog/2020/10/18/testing-the-form-block/

Actual behavior

I got a Preview link to https://eduardoistesting.wordpress.com/2020/10/18/testing-the-form-block/?preview=true

Steps to reproduce the behavior

1. Open the app
2. Select a WordPress.com site with a custom domain set to primary
3. Go to your list of posts
4. Click on the View button here: https://d.pr/i/HRMgM6/H5UHEugvhQ
5. Click on the Share link icon on the bottom left
6. Copy the URL or try to share the post on a service (Telegram, WhatsApp, whatever)
