This problem is very frustrating...
I am developing a SharePoint hosted add-in.
In this project a I have added a Web Part and code to the
When I publish a new version of the add-in (I am in round 34 at the moment) and add it to my test site, sometimes I can customize the home page and add the WebPart to it, sometimes it's not present!
I have not be able to understand the culprit.
In turns I have blamed:
- Some setting in
- Some unclosed tag in the html code in
I have not found the crux of the problem, I am suspecting something related to SharePoint online, maybe related to some conflict during Removing/reinstalling the new Add-in version...
Can you give me any clue on where or how to investigare further?
Maybe some sort of log...
UPDATE After some more investigation I have a strong suspect that the problem is random and is linked to the App installation phase!
In two (classic) sites I have installed the same app, and in first one the Web Part doesn't appear while on the second one it appears.
So, as new evidence, in the first web site I have disinstalled the App, then reinstalled it... and voilà it has appeared!
