Im not sure about this, cause as far as I know the wallets contain uni shoulf have been connected with the uniswap page or at least dapp like trustwallet if you want to know that you are eligible for uni.

If the OPs problem is the key, but still his wallet logged in on his metamask or imported then, he can still claimed it provided he has eth to provide for the fee.

Also is there a chance to still claim uni? I thought the claiming period ended.
