this issue comes and goes - and with different coins at different times - in an hour the above may be reflected correctly and my bitcoin balances will be wrong instead.
I've identified the scenario. If you have multiple addresses and the check for one of them fail, the failure will not be indicated in the user interface. The last balance for the address will still be displayed, but no longer part of the total.
I will correct this in the next release, to indicate if there was a failure and let the total value assume the last known balance for the address that failed once. After this change, you will always see the total balance correctly.
it seems to error now on anything with more than 2 addresses
