Cannot withdraw EMB from Overline wallet

Hi, so, whenever I try to send EMB from Overline wallet (downloaded linux version) to my wallet, the transaction stucks on loading and doesn’t send anything. When I tried it with browser Overline wallet, I get RangeError: private key length is invalid. Can anyone please help me/Did someone managed to solve this issue?
Thanks for any advice!

Got around it after several hours by directly importing private key in MetaMask. But man, Overline, fix your wallet.
