It is a Ledger issue. they don't support Polkadot spec version 23 as of yet (the upgrade that went in this morning).

Generally it would not created a massive issue, however the tx version was also bumped - so the Ledger app needs an upgrade (as/when available).

[zachalam]

No TX can be signed right now. Bonding, staking, transferring, etc. I understand the point about ledger spec version 23, however can we roll back to the previous version until this is released? Technically anyone dependent on using a ledger/polkadot apps is locked out of their account.

[jacogr]

There was a runtime upgrade. On the chain. Nothing the Apps UI can do to rollback the chain upgrade as voted in by democracy on the chain.

See block https://polkascan.io/polkadot/block/1603423 - that is what the Ledger does not support. On-chain runtime 23 applied in this event https://polkascan.io/polkadot/event/1603423-2.

Should we wait for an update from Ledger? Or polkadot-js? Or another onchain upgrade?

[Swader]

Ball is in Ledger's court. Workaround here, or just wait a few days.

@Swader Thank you! God bless you

Closing, the updated Ledger app for Polkadot is available in the Ledger store.
