If for any reason your app freezes, we suggest you just delete it from your smartphone and re-install it from the Android Play Store or Apple App Store, depending on which phone or tablet you're using.
If you're having problems with playback, please first ensure that your internet or WiFi signal is strong and try playing your session again. If this doesn't work, then please try re-installing your app.
If you continue to experience any problems, then please contact our help team at firstname.lastname@example.org.
Thanks for your patience.
