MeetUp is compatible with most mobile clients, however, on newer models of mobile devices, it may be necessary to disable the BLE function on MeetUp to improve the pairing performance. You can do this using the Admin Tool, see the article, "Can I change the Bluetooth or BLE settings for MeetUp?" for more information.
Please note that disabling the BLE function will disable the ability to use the soft remote.
If you still experience issues, please contact technical support.
