Advanced Gas Control for MetaMask on iPhone?

Hi guys

I have finally begun my Uniswap adventure, and have 5 pending transactions through the iPhone MetaMask app, all now many hours in waiting.

I checked etherscan, and can see that the gas price was, and remains, far below the Ether Gas Station suggestions. (One of the transactions is pending at 14 Gwei, but the gas prices have since gone up significantly - in the 36-46 range atm).
I cannot find a way to access the advanced gas controls using MetaMask on my iPhone - (There is no option in the settings).

Please can someone help and advise how I can manually control this moving forward?
And/or if there is some other way to get these transactions done.
I shall be extremely grateful! :slightly_smiling_face:

Thank You!! :pray:
