The Metro feed is now working. Thanks Intuit & Metro for sorting it out between you.
Procedure
1. Disconnect the old feeds. You will not loose entries. Thanks.
2. If during the period the feeds have not been working (just over a month) you have manually entered bank transactions then go into the account register and make a note of the last date you did this. Check your bank account to ensure you have manually entered all bank transactions on this date.
3. Reconnect to bank account(s) to the new feeds. It will ask you what date you wish to start from. If you have made manual entries then enter the day AFTER the one you noted above.
4. All the newer transactions will now be imported. Add or exclude the transactions in the list (as you used to do). If the balances do not then reconcile then you need to check for any duplicated transactions around the date you specified (unlikely).
