Still trying to get to the bottom of this. BW works if I visit https://portal.adp.com/. It redirects to https://signin.online.adp.com/ but this particular form has static fields unlike the one I’m having trouble with.
UPDATE: So if I manually tweak the URL from:
https://online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN
To:
https://signin.online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN
BW works on this different form and I’m able to login with Firefox ESR 128 on Windows. The BW app still doesn’t work with this form on Android.
