It is nearly impossible for me to review a Rover Card after I send it to my customer because the picture frames freeze. Is there a fix?
The cards work best when you are connected to WiFi and it's always a good idea to only send 1 picture per card. If you attach more than one the files size becomes too large and can hang up. If you wish to send more pictures during a visit just text them.
Your Rover card pictures freezing on your iPhone may result from iOS system issues. To solve this problem, you can use professional iOS system recovery tools such as https://www.tuneskit.com/ios-system-recovery-for-win.html (TunesKit iOS System Repair) to fix your iOS system, thus making it work again.
