I wouldn't say you're kicked out by the online system. As I mentioned upthread, if you parse together the several posts I made, I generally fall under this third situation: I receive reduced SS retirement benefits on my own account because of WEP, but never applied for spousal benefits because I would have been barred by GPO before this new legislation, shortly to be enacted when the President signs the bill.
I tried to apply online for spousal benefits with all the relevant information perhaps still in the system for SSA to process my application. The system told me it couldn't continue to process my application on December 27, 2024. I then called SSA and was told by the representative that for those who are currently collecting benefits, like me, the application has to be completed by an appointment and that the only appointments SSA was taking for these applications was over the phone. I scheduled a phone interview with SSA and the earliest date it had for me was February 19, 2025. Later on December 27, I received an email and text confirmation of the interview/appointment.
Yesterday, I received a notification in my MySocialSecurity message center with instructions for the phone interview. These basically said SSA will make every effort to call you at the appointed time, please have requisite ID information, and make sure you have the right bank account information for payments to you! Nothing odd about this boilerplate information.
We're so close to the finish line and I don't understand the incessant doubt (and now some bits of misinformation) seeping into this thread. Everyone's situation is likely to be different, even if there are common issues affecting us. For example, it could be that some of us might have to present marriage certificates (especially if the name on your Social Security Card is different from the name of the spouse whose record you claim spousal).
