If the profile form will not save, the most common cause is a validation error on a required field.
The profile form validates your name, professional headline, based-in country, active-in countries, Mission languages, interests, and LinkedIn URL before it saves. If any of those is missing or invalid, the form shows a field error and does not submit.
A LinkedIn URL must look like https://linkedin.com/in/... and must be a real public profile URL, not a private or internal link. Your Mission languages and interests must include at least one entry, and your based-in country must be selected.
If the save action fails after validation passes, the page shows a server error message instead of a field error. That message is usually a Supabase error code and description, such as a transient network error or a conflict on the profile row. In that case, retry once, then refresh the page and try again.
If you were signed out or your session expired while you were editing, the save action may be blocked. Sign in again and return to the profile page before saving.
If your name is missing or your profile is otherwise incomplete, some Mission features may still not match you correctly even after you save. Complete your Mission languages, interests, and location so the product can match you to relevant Missions.
If the profile picture selector will not save, confirm you selected an available picture from the connected account options and that the save button is enabled. Picture save errors show their own message separate from the main profile form.
