Routing is generally an issue of the nodes between you and your counterparty not having the liquidity to make the payment. Channel analysis tools help to pick the best peers to open channels with. Autopilot on LND is a good feature. But, it's all about picking peers who keep their channels balanced well for their routing needs.

I haven’t done any channel balancing. Maybe that’s the issue 🤔
I don’t know how 😅
It doesn't need you to balance nothing if you have outbound liquidity.
That only matters if you are routing other People's payments (like you hope your peers will do). But since you can't see their peer channels, it's impossible to know outside of asking them or your payment failing.
