Spend limit permission not recognized #137

Open sacalo opened 3 years ago

sacalo commented 3 years ago

It seems that the spending allowance is not recognized if it's already done before starting the exchange.

This is what I did: I wanted to exchange aUSDT for aUSDC. When I clicked "Sell" button, metamask asked me to approve spend limit. I edited the amount to a 1% more than I wanted to exchange. At the next step I saw a fee of 50usd, so I cancelled the trade, but the spending allowance is already confirmed. Now, if I try to start again the process, it asks again for the spending limit aproval, even though it's already approved.
