Not sure, but earlier I looked it up and apparently Zenphones get really good LineageOS support.
Maybe they were at one point, but the Zenfone 8 was never carried at retail in Canada, and Staples doesn’t currently have any Asus phones in stock.
Am I right in thinking that lineageos support doesn't really have an "end of life"?
At the end of the day, lineageos is best effort from volunteers, and you should weigh that fact when you decide what you want to use day to day.
