🐛 | Bookable Calendar | User warning: Invalid placeholder (langcode) with string: "Your booking is confirmed" in Drupal\Component\Render\FormattableMarkup::placeholderFormat() (line 245 of /var/www/html/web/core/lib/Drupal/Component/Render/FormattableMarkup.php)
@mikee did you have a solution to this in the end? I'm having exactly the same issue. Have tried reinstalling the module.
@mglaman I used your lenient Composer plugin to get the Commerce API module installed in Drupal 10 however I cannot tick the checkbox to enable the module under Admin>Extend "This version is not compatible with Drupal 10.1.2 and should be replaced". Any way to circumvent this?
