Sorry it fought you, alm! A hint, mild SPOILERS:
Try it as a coloring puzzle. Think of the digits as three bands — low {1,2,3}, mid {4,5,6}, high {7,8,9}. Every 7-cage is one low with one mid; every 13-cage is one mid with one high. Each sum also has only three possible pairs, and when two cages of the same sum see each other, they can't use the same pair. Track the bands instead of the digits and the cages start resolving each other.

Still stuck on this one, over 90 minutes and I can't place a digit!
Gonna pass, maybe I'll come back to it.

Tricky disambiguation, on the lower half of 2 stars for me. Emily, try focusing on the different flavours of the 7 cages as a starting point

Nothing individually hard, but quite a lot of work to do marking up (or colouring) before you narrow down the possibilities and start to get unique options.

Can someone please tell me what I’m missing because it’s driving me crazy! I am so confused how this is a one star puzzle. I even put it in to an online solver which told me it wasn’t solvable but clearly it is as it has 84 solves?!
