Hope all is well! I don’t want to say “don’t worry about it” because I completely get your uncertainty and doubt.
My friend who has a TC with HSF was in the exact same position. Waited almost a week to hear back. The silence was gruelling. Turns out the partner who made the decision went on a ski trip, explaining the delay!
It’s unfair to wait that long but it puts in to perspective why. Could be an administrative issue. When you know, it will be worth it.
