it kinda depends on wheres the issue, like is the actual release timing the issue or is it the fact there cam be various releases on one hand that is akward or is readinf the various releases hard or a mix of them?
reading anything at all: start playing basic LN where its just one long ass LN and then short tiny ass LN amd work from there
release timing: if you have percy, get rid of that, and learn to read. i think reading is easiest if the LN body and LN tail are as big as note because that way its clearer when to release
releasing your fingers: this one can only really be play more, ig do same as reading anythibg at all advice and work on that
on the off chance youve played improvement focused map pack charys for a while then you can do what i do and play LN release where the whole challenge is releasing LN whicb may or may not work
