I got the solver a couple of days ago.
So far I'm running hands that I was unsure of the best way to play them, then getting the general idea behind the solver solution.
I keep practicing>saving hands for the solver>review and repeat.

I was wondering if there's a recommended "meta" way to use the solver that I'm not aware of, or is what I'm doing fine?

What you are doing is fine indeed. Make sure that you are not focusing on the little things tough. So don't solve and then follow just your hand and then say something like "Ah, i should have bet 30% instead of 60% here". You mainly want to use the solver to undestand how poker is player on a macro strategic level, so that then you can deduce how the precise plays should be played by yourself as you find them. Always think about what the players should do in any spot and then check if the solver is playing close to that strategy. So your thinking should be more along the lines of "Well here our range is betting small because it puts max pressure on villain's weak holdings while risking the less possible"

Thanks, I wasn't looking at V's range compared to my sizing, I'll do that

This is probably the most common way people use solvers, and at the same time, the worst way to actually use them. You can use your hand history as a guide to find a specific spot you aren't sure of.

Let's say you were XR on the turn and didn't know what to do and folded. You check your solver and see that folding this combo is fine. What did you learn? Not much.

Now, instead, go back to the flop. Let's pretend this was BTN vs BB SRP. What does your flop strategy look like? What should it look like? Should you have a checking range? What size is the best? Why does the solver take a specific strategy on the flop? How does the solver counter this strategy? etc...

Once you have figured that out, now you move to the turn. What turn cards should you be barreling? What are the best/worst turn cards for you and your opponent? etc...

You need to be asking these types of questions and taking this approach instead of just clicking through the solver, seeing the way you played is OK or not, and moving on. Once you start to understand the strategy the solver is taking, you can start to recognize patterns and start extrapolating the ideas to other spots. Everything the solver does is for a specific reason and based on math and the ranges and how they interact.
