OK, this may be a bit embarrasing...
The Wallet program won't fill in automatically the necessary credentials to log in to a bank when in Safepay. The boxes stay empty, and I have to type in both login and password manually.
In fact Wallet does not seem to be able to automatically fill in any kind of information from the 'online banking' tab, only that from the 'websites' - but in Safepay the latter does not work either.
Is there a way to somehow configure these two facets so that logging into my bank will not be too much of a hassle?
