I have developed a word add-in and promoted to add-in store. I have implemented auto open task pane as described in add-in document(https://dev.office.com/docs/add-ins/design/automatically-open-a-task-pane-with-a-document) but my add-in pane is not loading when I open the document, I have to every time click the Icon that was placed when I installed(added) the add-in from store.
IS there any other factors controlling auto open functionality? Please help me.
The ID after webextension needs to match the ID that's in the manifest submitted to the Office Store. When using the snippet above this fails because the store id - wa104381318, does not match {AE9B1970... which you have above.
Changing it to {B95BF4FD-FCD8-4064-BF56-7B6EA9938F9} should resolve the problem.
