If you're having trouble uploading a photo from Facebook, make sure your photos are in a public album or at least visible to your friends (not only you). You may also try moving the picture into a different album on Facebook.
If you're having trouble uploading a photo from your phone, make sure you've allowed Tinder access to your phone's photo album. If you denied Tinder access to your photos, go to your phone’s settings, find Tinder, and enable photo access.
If the issue persists, please try again at a later time.
