If you happen to watch your CUB farms and dens with MetaMask on mobile, as per my article yesterday, you may have to pay attention to your fees. I already wrote in yesterday's article that there might be a problem with fees, but it was merely an intuition, I didn't really have time to check it out. 

But this morning I did a transaction per transaction comparison, and, to my surprise, I realized that transaction fees on MetaMask mobile really are as 10x times higher than on desktop. 

Here are the screenshots of MetaMask mobile for "Compound" in the den, and "Harvest" in the farm:

Transaction fees are paid in BNB, as you already know (or I hope you know). At the moment of writing, BNB price was $267.

Compound: $267 * 0.001612 = $0.430404
Harvest: $267 * 0.001993 = $0.532131

There's basically a 10x difference between those mobile fees and desktop fee. I looked into MetaMAsk mobile for some settings related to how to set the transaction fee, but I ony found this, after you tap on the Edit link, next to the Netwrok fee label:

I suspect there is a setting inside MetaMask that treats BSC just like Ethereum and doesn't pick up the correct transaction fees.

If anyone knows of a way to normalize these fees, do let me know.

Until then, feel free to check your farms and dens, but be wary about compounding or harvesting while you're on mobile.
