Downie extension keeps disappearing randomly and needs reinstalling all the time

I’m having an issue on multiple machines, the Downie extension keeps disappearing randomly and needs reinstalling all the time. It’s an extension that requires the dev mode, and it keeps doing two things all the time and it’s driving me insane:

  1. It unpins randomly…
  2. more often than not after a few days, it’s simply GONE.

Can you please look into it and fix that awful bug please? Is anyone else having this issue? It does this on all my Macs and it’s driving me insane. I use Downie through setapp.

Thanks in advance,
Cheers
