Why can't I delete a template?
When deleting a template via the trash can on the overview page, all languages of the template will be deleted. To remove only 1 extra added translation, click on the edit icon, select the relevant language and choose in the options menu to remove the language.
If you receive the message that it is not possible to delete a template, then the template is still in use. Remove completed/expired payment links and adjust active payment links to remove the template.
