20+ followers gone?
I am so confused, I was using my computer and it was really slow, so I reloaded it and it said that I had 27 followers! I only had 3 before. Then I reloaded the page again and it said that I only had 3 again :(
Were you on someone else's profile before? I remember this happening to me, and it was because Duolingo had kept my count as the one of the user profile I had been on before.
Possibly just a glitch? This has never happened to me, so I can't really give advice... When you had the 27 followers, were your 3 constant followers included? If not, than it could have been a glitch or you could have been on someone else's profile, like Ik_Ben_Een_Appel said.
