Hi m.guy,
The update should have updated your screens and the BillPayment screen on the new version of Method should show that it has been updated 21 days ago. If you go to Customize > Screens and you type in the screen name field "Bill", you should see the screen name listed in the search results.
In regards to the version that you are logged into, we have removed the staging site and now everyone will be logged into the latest version which previously was the February version.
Try loggin in right now and let me know if the BillPayment screen for you has the same information that I had described above.
I hope that this helps.
Ronen
