We are working on it, but its currently hard for us to test the various mobile browser integrations. For now the best way to cash out tokens is on desktop using Chrome or Firefox.
Note: if you use the Kiwi browser for claiming tokens it will not work correctly and you won't be able to complete the transaction. If you have started a "Claim Tokens" transaction in Kiwi, you will be able to complete it using the desktop browser if you connect the same Metamask account.
