version 16

  1. Version bug?

    We have a V18 3cx installed but in the Portal the subscription still shows V16 if i read that correct. In the 3cx console it shows V18. Is this a different Version number in the screenshot below or is there some type of bug or something we did wrong when updating to V18? Greetings
