If you can't continue to sign after the iDEAL payment or iDIN verification, this is because we have lost the 'connection' between the banking environment and viewing the document due to a setting on your device or PC. Without this connection we cannot legally validly sign (or have a digital signature signed).
Causes:
The process is done on a smartphone with another browser than the standard browser, such as Safari. View the settings on your device to find the standard browser.
The process is started in an in-app browser. This happens e.g. with links opened from the Gmail app. If this is the case, copy the link from the email and paste it directly into your standard browser.
We advise people to complete the process on the PC.
Doesn't it work on the PC?
The cause may be that the PC is protected by a virus scanner that controls all banking in a separate secure browser. Virus scanner Kaspersky does this, for example. We advise you to turn off the separate banking environment of the virus scanner.
If you can't successfully complete the signing process try it on another device or contact the organisation that sent you the signing request.
