Need some tips/tricks for playing with on a 12 string

So I recently started playing and got a 12 string as my first and honestly I feel as if my fingers isn’t long enough to reach the lower E, A, D strings on top ( I have the strings paired ). So my problem is I cannot put my ring finger on a tab bc it’ll go in between and separate the paired string and it gets frustrating. Also i don’t have enough finger strength to put enough pressure on the lower E, A , D strings and they buzz when I play. Any tips ?
