How to connect my Pillar wallet to PoolTogether?

1. Pillar and PoolTogether

So, I am trying to login with my mobile wallet in PoolTogether, but I don’t see Pillar in the list of the wallets offered by the service. Any idea how to do that?

2. Gas fee adjustment

Since the gas fees are up again, if there a way to adjust the fees like in MetaMask? Or at least choose between Slow, Medium and Fast?
