I use lineage on oneplus phones and have no problems. I can't do internet banking and a bunch of other non-free things, but really, who needs that? I have a web browser. The only thing that doesn't work is google meet and google docs and google drive because they intentionally break the mobile experience in the web. But there is a simple solution. Simply don't use google services. If/when my employer demands that of me (occasionally I hear murmurings) I just tell him I'm online 9-5 on my laptop and if he needs me he can call. I'm happy with my lineage.
