So, this is a nasty new feature, apart from the very questionable introduction of this feature, I've had this operational issue + work around.
My original savings account/saving goal account did not have the option to be converted to a regular bank account
This gave an operational 'challenge' because normally nearly all my money is in saving accounts. If I need the money I'll take some from the savings account.
so I've found a workaround:
1) I've created a new savings account, which had the option to be transferred into a "regular bankaccount"
2) I've moved all my savings into that new account.
3) I've converted the new account into a regular bank account.
I'm aware that I will not be getting interest but, being able to access my money is more important than interest
