After I finished reading a story today, I tried to go to my Followed Author list and got the notice of No Followed Authors Found. To access the list, I come from My Stream and select the Followed Authors link on the upper right of the screen.
This seems to have started sometime yesterday.
They're there, but I'm trying to locate the bug that's giving that message.
2021-02-20 ETA: Bug fixed. But, since it didn't affect all accounts, I'm not sure of the bug fix. Please check your following list and let me know if it's working as expected.
FWIW, I am accessing using an iPad and iPhone. Even after clearing the cookies and rebooting, it still is persisting. I have yet to try and access on my PC. Selecting an author's page that I have in my list still shows that they are followed along with the My Stream page is populated with the latest submissions.
Have you switched from free to paid membership? Or paid membership expired?
I had a similar issue on FineStories maybe 18 months ago and don't remember a real resolution.
