Update: Over the past few days, several Ledger users have informed me that they want to participate in the coinholder vote, but are unable to transfer their ZEC to YWallet. This issue stems from Ledger not updating the consensus branch ID following the activation of NU6, as documented in this thread.
Given these circumstances, I have decided to extend the eligibility window from Block 2,731,300 to Block 2,734,280, which will occur around 08:00 UTC on Saturday, November 30, to provide Ledger more time to resolve this issue so more users can participate. I have also reached out to Charles Guillemet, the CTO of Ledger, and asked him to urgently address this issue. I will provide updates once I have more clarity on the situation.
