It doesn't work on majority of Crypto Exchanges

Any special reasons for that? Auhty works fine but for most crypto exchanges (Biance seems to be the only one working) Protecc does not work. I tested on Kraken, MEXC, NovaDAX and Mercadobitcoin.

When I manually add the key proveded by the exchanges, the pin generated is not recognized. When I try to add it via QR Code, the "Key" field on Protecc stays red (error) and the copied code is way larger than usual (way lager than expected by Protecc?).

Is it some kind of newer security model or something that these companies are using?

Thanks in advance and I hope I wans't too confusing, english is not my first language
