A. To change or delete your main photo in Loosid, first, open the app and navigate to your profile by tapping on your profile icon. Look for an option that says 'Edit Profile' or 'Change Photo.' Tap on it, and you should see your current main photo. Select the option to either change or delete the photo. If you want to change it, you can upload a new image from your camera roll. If you want to delete it, look for a trash can icon or a 'Remove' option and confirm the action.
B. If the app does not allow you to change or delete your main photo directly, try logging out of your account and then logging back in. Sometimes, refreshing your session can resolve minor glitches. If the issue persists, consider uninstalling and reinstalling the app, which can reset any stuck settings.
