can't add liquidity to USDT-UST pool

Bug Description
User having issues adding liquidity to USDT-UST pool. We have a chat with him in Discord (#ticket-brandon--radar).

Steps to Reproduce
Trying to add liquidity to USDT:UST
the market price is within my selected price range
I'm still receiving the error that the market price is outside your specified price range

upon entering an amount for a single-asset deposit, I can see, behind the error message, the correct ratio between USDT:UST given the current price

upon pressing the Add button, I get this error in the console, and no confirmation dialog pops up

this is the URL where I'm adding liquidity for this pair https://app.uniswap.org/#/add/0xa47c8bf37f92aBed4A126BDA807A7b7498661acD/0xdAC17F958D2ee523a2206206994597C13D831ec7/500
allowances are set properly, I have sufficient balance of both assets, etc etc
interacting directly with the contract works fine

Expected Behavior
Adding liquidity works

Additional Context
User tried different browsers and addresses and issue is always present

Start at the add-liquidity flow for the USDT:UST URL in the issue and reproduce the selected-price-range error while checking the browser console. Trace the failed Add action and verify that a valid deposit reaches the confirmation dialog and can proceed successfully.
