After watching the todays stream i have picked up, that you guys having problems with Ledgers showing 0 Balance after Ledger has updated their software to support Segwit. Today i had a phonecall of a friend i brought into crypto at the beginning of the year. He also had the problem of a non working / zero balance wallet with his ledger. After encircle the problem with him on the phone i came to the conclusion, that its only the fault of the software. So i suggested him to do the following steps which had fixed the problems for him: 1. uninstall the google chrome wallet app 2. uninstall google chrome 3. reinstall google chrome, make shure the ledger wallet app is not present! 4. install the ledger chrome app I guess its a problem with the automatic update of the Ledger Chrome App and the stored preferences/database/addressfiles on the local computer. You need to make shure to wipe/uninstall all the local stored data on your computer and reinstall the Ledger toolchain. There is no need to upgrade the firmware thats on your Ledger Wallet USB device (if you allready have latest Firmware installed since Bitcoin-Cash update). Another chance would be to clear the local browser cache/local browser database, but i did not checked this way to fix the problem. Have fun, hope this helps.
