I have no idea what will happen in terms of getting eligibility letters, paying for the plan, follow ups, etc
Right now it's backed up. But normally......... you would get an eligibility letter within a short time (minutes to hours). It will be emailed to you, but also will show up via a link on your dashboard. It's the FFM's own eligibility letter. You will also get a copy of the app's data like it was sent to the FFM. To pay for the plan, you click a button on your dashboard that takes agents through the "back door" to the FFM (avoiding account set-up, UN & PW with the verification emails). From there you can click to pay the premium. Some carriers don't use the FFM pay the premium method, but many do. You can also look at the app, and view the plan's name, effective date, etc.
By the way, to be fair to the WBEs, you can use a "back door" link to enter the FFM with other WBE's like ACAExpress, and you will also get a quick eligibility letter with them, too.
