My theme is using Bootstrap barrio theme (bootstrap_barrio) as a base theme. I'm trying to override Drupal commerce template modules/contrib/commerce/modules/order/templates/commerce-order-receipt.html.twig
and it's not working for me. Even I copied that file to drupal/web/themes/my_theme/templates ,cleared the cache, Commerce is still using original template file from commerce module.
What puzzles me is that base Barrio theme also has that template and it's also not used?!?
Do I have to set somewhere what theme should be used for email templates or something? Overriding other modules templates (including commerce templates) works fine. Documentation says "The email can be customized by overriding the Twig template in your theme just as you would any other template".
