I own the original PinePhone, and it’s nice to tinker with, but honestly it’s far too slow to be usable on a regular basis. Perhaps the PinePhone Pro is slightly better, but most likely still not good enough.
Couple that with the other issues described by @carzian@lemmy.ml , and it’s pretty clear why it failed.
Even in Firefox all streaming platforms I’ve used in the last couple of years worked just fine.
