Error handling for fields which are accessible but not visible

Depending on your Salesforce settings, sometimes you can have customs fields which are generally accessible but not visible. This can cause issues in our interface. Hence, Weflow now regularly checks which fields and objects a user has access to and what kind of access (i.e. read or write access).

This is a backend change, and you will unlikely notice any differences while using Weflow. However, it is a major improvement to ensure a 100% stable user experience.
