Openmask connect Ledger to interact with dapps resulted in transaction funds getting stuck,cant get token return

[dccboo]

Describe the bug
When I used openmask wallet with ledger to add liquidty in STON.fi,is failed with "The tokens ratio has already changed,Please return tokens and start liquidity provision process again."
but I when I click "return",I cant get USDT back with ledger cause that openmask wallet shows " App Ledger 2.0 is not support custom transaction".
This doesn't make sense. If Ledger 2.0 doesn't support dapp interaction, my USDT must cant be added to the STON.fi liquidity pool and caused it to get stuck.
Are there any solutions available for this issue?
