Dropbox_for_SF duplicate Schedule Job Error

[Namanpreet]

I am getting the following errors from one of our Salesforce customers who is using the Dropbox Salesforce integration app.  Any thoughts on what is going on here, and how this might be fixed?
Thanks Naman

Hi there @Namanpreet - sorry to hear about this.

May I ask if you're a team member on the account that's having the issue or a team admin? 

Could you send us a screenshot of the exact error you're getting so that we can have a visual too?

Any additional information is more than welcome!

I am team admin

@Walter We have recently changed a few users' username and email. Now we have observed a lot of apex jobs are scheduled entitled "FISCHEDULE - Change Owners xxxxxxxxxx ” from one of those users and we are getting this error.

Thanks for the additional information and the screenshot too @Namanpreet 

Would it be OK if we sent you an email to have a further look internally?

[Namanpreet]

Sure @Walter.
