24H2 has brought new security thing on connections and you did adopt My Cloud Home to that. Now there is no 40 MB/s cap. It is normal speed of about 110 MB/s. I did wait for firmware for EX2 Ultra with that adaptation but time passes and there is no fix. For MCH that was I think about one year ago. I do not now why is problem to make same thing for EX2 Ultra. Please do it, there is need for speed.
