No, it never fully recovered. One day, a few weeks later, some switch flipped again and it went from 1% of it's previous views to 10%. Now it's all over the place and I'm less interested in TikTok. Having 22.5k followers means nothing if it's actually TikTok that decides who's going to see my posts and they don't even show them to my followers.
I'm here to ask the same question! After about 9 months my account reached over 21k followers and was getting thousands of views per post with a few in the hundreds of K and one at nearly 6mil. About two weeks ago my posts stopped appearing on the FYP and views are down to about 1% of what they were.
Have you been able to figure out what's going on? Were you able to pin the change down to on particular post? I'm able to do that but I can't see a problem with the post.
