Addins aren't loading in Excel WOPI about office-js

Hi @SirDavenport, Thanks for reporting this issue. Could you please tell us more details about how to repro this issue? Such as which add-in has this issue? Thanks.

Hi thanks for taking a look. The addin we are loading through WOPI is id WA200003648. And again, this is only happening in Excel in WOPI when a second user is opening the document. The addin loads for the first user.

Hi @SirDavenport Thanks for this details. Sorry, I can't repro this issue. Are you get this addin from AppSource and share someone the doc? like: https://appsource.microsoft.com/en-us/product/office/WA200003648?tab=Overview. Is it a solid repro in your side? If you can identify a user condition or have a solid repro please feel free to comment here again that will help our investigation and get sooner to the issue.

Hi @shanshanzheng-dev, you are using a WOPI implementation, right? The issue is not reproducable in the desktop. Only Wopi in Office Online. If you want, I can private message you and give you access to one of our environments, because I can reproduce every time I try there.
