I just found this thread since I wanted to post the response I received from VW. They make it sound like they might change their mind. But honestly, I'm sceptical. Several apps stopped working for me lately (public health insurance, public car registration app, a banking app). A year ago there wan't a single app that did not work!
The introduction of the current integrity checks was not based on an assessment that a particular operating system or device configuration is or could potentially be insecure. Rather, these measures are part of a broader security and data privacy concept for the Volkswagen App and the associated vehicle services.
As part of the review of the previous architecture, potential data privacy and security-relevant aspects were identified in connection with third-party access to vehicle-related customer data via unofficial reverse-engineering solutions. The current integrity checks were introduced to further strengthen security, transparency, and control when accessing customer accounts, vehicle-related services, and personal data.
The integrity checks are part of these protective measures. Their purpose is to ensure that access to customer and vehicle data, as well as security-relevant vehicle functions, only occurs from device environments that meet the integrity requirements defined for the use of the Volkswagen App.
As a result, it may happen that device configurations that worked in the past no longer meet the currently applicable integrity requirements. In addition to the operating system itself, other factors, such as the integrity status of the respective device environment, can also play a role.
We would also like to clarify that this should not be understood as a statement that your device or your configuration is fundamentally insecure. Rather, this reflects the security and data privacy requirements that Volkswagen currently applies to protect customer accounts, vehicle-related services, and personal data.
Your feedback has been forwarded to the responsible product and development teams and will be taken into account there. We are continuously working on solutions to align the needs of our customers with our requirements for security and data privacy.
Thank you for your patience and understanding!
This thread is quite long now. Can somebody tell me what the community experience is regarding a good next step? What can I respond to them and who else can I write to?
P.S.: still not able to log in on 4.2.1
