That's for recovering your Follows. It's a super useful tool although may not be useful in this case.

I think Mags is talking about followers.

The count of your followers is a complex task & involves your client literally counting the npubs that have you in their follow list. It's unlikely they've been lost, more likely that Amethyst has just not found them yet.

I recommend not giving a shit who's following you & focus on sending & receiving a strong signal. I lost my follower count on Amethyst too but then 69 were found 😂 🤷
