I’ve run into a similar issue with my second character as well. It can be really frustrating to have to go through the quests and campaign again just to unlock Strand/Stasis. While I haven’t found a direct solution to make the boost/skip option appear on secondary characters, I’ve used [url=https://wowvendor.com/shop/destiny-2/]Destiny 2 boosting on PC[/url] services to help speed up the process. These services can be a great way to bypass the repetitive grind and get your character where you want them to be. Hopefully, Bungie addresses this issue soon so it’s easier for all players to manage their secondary characters.
