It doesn't seem to work on 1.16.5 after migrating my account, was working till this point now it just keeps the same skin regardless of if I change it

A fix has been applied to the 1.17 version for this issue. I am still yet to apply this fix to previous versions.

Brilliant, I look forward to it.

Ur doing an amazing job on this mod, really great work :)

This should be fixed on the latest fabric and forge 1.16.5 versions on curseforge. https://www.curseforge.com/minecraft/mc-mods/skin-swapper/files
