Coldstorage wallet issues

I have Litecoin on a coldstorage wallet, but cannot confirm amount using Coinomi. Ive used this app for a while with no trouble, but now it wont show the amount nor say that the wallet is empty (as it does for wallets containing no funds). Is anyone else having trouble with coinomi and litecoin?

go to ( ) and type in your public key and it will show you your or any other litecoin, bitcoin, eth …etc address you type into it

also is a good one too…

keep in mind not to type in your private key…your public key is what is holding the coins and the private key is what spends them
