I'm on the support team so I'm not actually on the dev team. But I expressed my interest in development, so I get to partner with a Sr SWE who scopes and guides me through some tickets. I usually get assigned 2-3 tickets/sprint but they're not actually on the sprint board so that KPI's don't suffer if I miss the sprint deadlines. I pretty much work on them whenever I'm free but I try to be diligent and finish them within the sprint period anyway.
She's on PTO for 3 weeks. To my surprise, the team still assigned me some tickets this sprint. I want to work on them but I'm stuck on one of the tickets. Should I wait for her to come back? Or should I ask other devs? I don't want to appear burdensome since I'm not actually a part of their team. Plus all their devs have 5-20 YOE so that makes it more intimidating.
