PreMeetingService unitialization fails

[aliaksei.luferau (Aliaksei)]

Description
App use CustomizedUI / C# wrapper and works as a host

The program successfully goes through all the stages described here 3. Schedule, Edit, and Delete Meeting Sequence

ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.Initialize(initParam) == SDKERR_SUCCESS

ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap().SDKAuth(authParam) == SDKERR_SUCCESS

OnAuthenticationReturn(AuthResult ret) ret == AUTHRET_SUCCESS

ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap()Login(loginParam) == SDKERR_SUCCESS

OnLoginRet(LoginStatus ret) ret == LOGIN_PROCESSING
OnLoginRet(LoginStatus ret) ret == LOGIN_SUCCESS

ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetPreMeetingServiceWrap().ListMeeting() == SDKERR_UNINITIALIZE

If app repeat the CZoomSDKeDotNetWrap.Instance.Initialize(initParam) call before ListMeeting() calling, then everything works well. Is this behavior by design or this is some kind a SDK issue&?

Same questions here

Hey @aliaksei.luferau,

Thanks for using the dev forum! It is nice to see you again

There are known stability issues with the preMeetingService and we no longer encourage developers to use it. Instead, we recommend scheduling/creating/deleting meetings through the RESTful API: https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate

Thanks!
Michael
