Touch App Known Issue - pdk.io app running in the foreground

• Touch credentials in the touch App will not work reliably when a user has the pdk.io App running in the foreground. 
• If a reader is added to a system after touch credentials are issued to users, there will be an unspecified delay in existing credentials that will work with that reader. 

Workaround: The user must launch the touch App in the foreground which will immediately refresh their credentials.
