Theme development

Hello, I have question about theming emails. I installed Symfony mailer, because with this module it should be possibel to send themed/html emails. But all emails still look the same like before. Specifically I would like to be able to send formated confirmation emails for Drupal Commerce. Right now all the mail are in simple text format. No matter how hard i try, I am unable to find the solution to send html emails with Symfony mailer. Could you help me?

I am usind Drupla 9.4.8 and Symfony Mailer 1.0.0-beta1

I am using an entity reference field to display author names on our site.  I added a 'published_name' field, and referenced it to the Author taxonomy. The published_name taxonomy field is within the a custom profile called 'Writer Profile', made using the Profile module. The Writer Profile is added as a rendered entity on admin/config/people/accounts/display. The writer profile fields display on the user's profile page, but I would like to do is customize the twig so the writer profile fields are displayed on the user's profile the way I want.

Hello, I need your help. I am building website build on my own theme which contains e-shop (with Commerce v 8.x-2.31). On my local server everything works great, but when I deploy it to my live test server there is error when I try to add payment gateway for eshop.
In log, there is PHP error with this message:

Hi, I'm converting a Drupal 7 site to Drupal 9. It's a fairly simple theme and I've managed to install the theme in Drupal 9. However on going to the site, I recieve this error:

Hi,

I created a new theme project called "Portfolio theme explore" but it looks like the node has been deleted thinking "it is spam or something"

If you log in, you can find it from here

https://www.drupal.org/project/portfolio_theme_explore

Would someone please help and undo the node deletion?

I wanted to make a release and update few things.

Looking forward to your response
