Zoom Web Meeting SDK v2.8.0 Invalid Signature

[j.schoenemeyer (Jürgen)]

is your meeting created in the same zoom account like the Meeting SDK App?

'Signature is invalid.', with meeting number created by other accounts

Hi Gianni, Thank you for your help! Now, my questions are almost clear. Let me clarify one last thing. ZAK token is only used for START their meeting, so in my understanding, people can JOIN a meeting without ZAK token after SDK app is published, is it right ?
