In anticipation of the exciting Polymesh v7.0 release on November 20th, Ledger has updated the Polymesh app.

You must WAIT to upgrade your Ledger device until after the v7.0 release is live. If you upgrade the Polymesh app on your Ledger device between now and the release, the app will not work until v7.0 is live.

Once v7.0 is live, you will need to upgrade the Polymesh app on your Ledger device.
