If you select the wrong language while editing the travel proposal, you won’t be able to change it later. You’ll need to delete the current proposal and use the shared invitation link again to create and edit a new one.

Click on the three dots on the trip proposal you accepted
Choose "Delete trip"
Confirm by clicking on "Delete"
Note: This will only delete your version of the trip, not the supplier's original trip

Click on the shared proposal link
You will see a new proposal acceptance screen
