We have been using the app without issue on 2 slightly older iPads. The addition of a third has resulted in the third newer iPad losing connection with the host session mid song. After reading other posts we connected to the venue wifi which helped slightly although still the same iPad was dropped mid song, sometimes after a minute or so, sometimes it lasts for a few songs before dropping. Easily able to reconnect but it's inconvenient mid song. The new iPad is closer to the host iPad than the other one so it's not a distance issue. Could anyone help please as it is currently close to unusable.
