I'm following the tutorial at https://ringcentral-tutorials.github.io/sms-api-csharp-demo/?distinctId=201757107#3
Everything work fine when sending the Sms message but when I try the Mms example I get as compile error stating "Argument 2: cannot convert from 'RingCentral.Attachments[]' to 'RingCentral.RestRequestConfig'. The error is on line 56 of the above tutorial:
var resp = await rc.Restapi().Account().Extension().Sms().Post(parameters, attachments);
Anyone know the solution to this?
