Please check if your internet connection is working fine and Bluetooth is switched on. If both are functioning properly try restarting the app. If this does not work and if you are on Android, go to Settings > Apps, reveal System Apps and search for Bluetooth share (this can be named differently depending on model and brand). In the Bluetooth share information, tap storage, select the ‘clear data’ option and reboot your phone. Please note that this will disconnect your phone from other devices. If the above steps did not work and you airline has not communicated known issues, please contact us through the support page.
