I have not accessed my IOTA 2.5.7 light wallet in quite a few months, however I was finally able to get my full balance after a few attaches. I downloaded the Trinity Wallet (with Ledger) and transferred a few over to it from the light wallet. The amount shows up on Trinity but there is no dollar value. Also, I attempted to transfer a few back to the light wallet as a test using the ledger but get the message about NOT ENOUGH FUNDS to transfer, even when I attempt to send 1 Iota. Help!
Marcus, they have changed the API calls from IOTA to MIOTA. It's a known bug that will be fixed in the next update. "Will be fixed in next version. Just an bug in the API for fetching chart information."
