The language option for a tour package is determined by the default language set in the Setting page. After setting this default language, you cannot change it directly in the tour package form, if you are Starter, Launch and Growth package membership. But for Advance package and above, there is allow to select form multiple language dropdown list.
However, once the 14-day period has passed, the language option becomes fixed and cannot be modified through the platform. If you need to make changes, you may send email to us at care@travelscqm.com. To send an email, please read this article.
To enable this feature, you will need to upgrade your subscription at least the Launch plan. Please refer to How to upgrade/downgrade my subscription plan? for detailed instructions.
