It’s pretty visually apparent that the introduction of live PvP in December 2021 has affected FEH’s longterm sales NOT in a positive way:

FEH’s sales are still quite fine as the mobage it is, but this is definitely the most decline it’s seen compared to the previous 4 years before it. We’ll just have to see if they introduce a good new permanent mode soon enough, cuz SD was NOT it.

I’ve been really want to offload my alt account because it’s becoming more of a chore to maintain it, but it’s also linked to a Nintendo account I still have a use for, so… dilemmas, lol.
