This was reported on v2.2.9, the version currently available in Ledger Live. v2.2.9 is v2.2.8, plus some adjustments to accommodate Ledger firmware 1.6.1 made by the Ledger team.
Issue: Nano X Bluetooth communication is not working.
To Reproduce: Attempt to use a Nano X device with the Ledger Live mobile app.
QA Note: The solution will have to be QAed by using a development Nano X device on mainnet with the Ledger Live app. Only development Nano X devices can sideload (i.e. load without Ledger Live) applications.
