dirksche Hey there, new user here as well. I've got a very similar OS history to yours, but no Sailfish. A few custom roms in addition to Lineage, but that was several years+ ago. Really impressed with GrapheneOS so far, was delighted to find that everything in my use case just works, and works well. Some highly knowledgeable and helpful people here, and the response times have been fantastic from what I've seen.
Anyway, welcome and hope you continue to have a great experience!
