Additional disclaimer for SideStore setup on Windows: do NOT use the current SideServer application to go through the installation process, since apparently it fucks with the pairing file and makes WireGuard connection impossible.

Had a fun time finding this out after maxing out free account ID limits, and having no IPA's install on a younger brother's iPad. More experience for me, I suppose.
