there are many reasons to get a plex pass, but that isn’t one of them.
never buy or pay for something with the ‘hope’ that it will someday satisfy your needs/desires.
there is only ever what works now, and even that is not guaranteed (see loss of plugins/plexcloud/etc).
plex does many things well, no doubt. is it perfect, surely not.
are there other alternatives, maybe, but everything has it’s own pro’s/con’s for which only you can decide what best suits your needs/desires.
