I don't own any JLP, so I'm not 100% sure, but I think that it acts kinda similarly to those tokens know as "yeald bearing token", where the earnings aren't used to mint new tokens (which usually are then ditributed to the holders, who see their number of tokens increase) but are used to increase the token's value: so, intestad off seeing both your balance of tokens and total value increasing, you only see the total value growing, as every single token become more valuable with time.
That would explain why you weren't seeing your JPL balance growing, while their value was :)
I was told I needed to use the JLP multiply
With "multiply" you can do that trick (deposit, borrow, swap, deposit, etc) with one single tx: much quicker and easier! Same if you want to deleverage your position.
You can check my post for a brief introduction of the feature :)

Yup, that it, but I don't like it, I want to see more tokens :-) .I think I will use Jupiter Lend to borrow USDC and buy SOL when I think SOL is at a low point and likely to move up. I can deposit the SOL and earn APR while I wait, and then when it rises , sell the SOL to repay the USDC and see if I can have some SOL left over. I need to look about and see if I can get an apy on the SOL that is higher than the apy I pay to borrow the USDC
If you swap SOL for something like MSOL, BSOL, JupSOL, etc, you can get an APR around 7-8%. And if you want you can use it (at least JupSOL) with the multiply feature to get an APR even higher!
