In my LeoDex experience up to now, most routes I was interested in weren't available when I would have liked to trigger them - It can be linked to Maya Protocol having had a hard time with the Arbitrum chain for the last weeks, or simply be due to a lack of liquidity in the pairs I was looking for.
Normally, even very small amounts are swappable through LeoDex, it's not very probable that it was the hinderance's reason 🙂.
