A. For photo upload issues, first ensure that the app has permission to access your photos. Go to Settings > Privacy > Photos > Fruitz and make sure it is set to 'Read and Write'. If permissions are correct, try restarting the app. If the problem continues, check your internet connection; a weak connection can hinder uploads. You can also try reducing the size of the photo or using a different format (like JPEG instead of PNG) before uploading.

B. If the app still fails to upload photos, try logging out of your account and then logging back in. This can refresh your session and resolve temporary glitches. If the issue persists, consider uninstalling and reinstalling the app to reset its settings.
