excel-online(office-api): add-in not working when you re-add it from store

[fds-rpg]

When add-in is added from store, it works normally, however when it is removed and re-added, the app would not work anymore.

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Office on the web
• Host [Excel, Word, PowerPoint, etc.]: Excel
• Operating System: Windows 10
• Browser (if using Office on the web): Google Chrome

Expected behavior

the add-in from store works normally.

Current behavior

When add-in is added from store, it works normally when you interact with the taskpane, however when it is removed and re-added, the app would not work anymore. The only workaround to fix this issue is to reload the page.
The current action type we are using in our manifest is ExecuteFunction. We also do not have any actions that automatically opens the taskpane

Steps to reproduce

1. Open Excel web, then click "Office add-ins" on Insert Tab from tab list
2. Add FactSet for Excel (Early Access) from store
3. Click the FactSet tab and click "Insert Formula" ribbon button and interact with the taskpane
4. Close the taskpane and remove the FactSet add-in from "Office add-ins"
5. Add FactSet for Excel (Early Access) from store again, and click "Insert Formula" ribbon button
6. Notice that the app does not display in the taskpane and the taskpane only displays a blank, nothing happens when you click the ribbon buttons as well
7. Workaround: reload the page and the add-in will run properly.

Thank you for letting us know about this issue. We will take a look shortly. Thanks.

Hey there, thanks for reporting. This is by design and we would require the session to be refreshed as we don't consider it a standard scenario to remove and reinstall add ins in the same web session.
