In order to build an iOS app in Nintex App Studio, you must create a provisioning profile through the Apple Developer Portal. Please note that an account is required to create the appropriate certificates to sign iOS versions of Nintex App Studio apps.
For more information on generating provisioning profiles, see the Apple article Creating Provisioning Profiles Using Member Center.
The provisioning profile expires every year and therefore I am having to generate provisioning profile every year so i can create a distribution certificate. I have done this for past two years as users cannot open the app since the certificate is no longer valid. Is there a way for certificates to not expire (any other options)? How do i prevent the certificate to expire every year so when users tries to access the app it does not give them error?
