I am currently fooling around a bit with forge and ReactJS.
So I created a Custom-UI forge app via “jira-global-page” template, removed the static content and recreated it with
npx create-react-app
Without any further changes it will render to this:
BUT: Interestingly it is only rendering when using
forge tunnel
without tunneling the site is empty 
I wonder why this is the case? A bug in the minification process perhaps? 
Did you build and deployed the forge app? Tunnel serves the app from your local environment. Without it you need to build the app and deploy it.
Sure 
I don’t know that I can use an app in cloud without deploying and installing it anyway
But yes, I do a deploy: nothing is rendering and after that I do tunneling and the app get’s rendered
I can try to uninstall, delete, redeploy and reinstall it - but I do not expect a change 
EDIT
“uninstall, delete, register, redeploy and reinstall” → done => same bahavior…
if you wish I can zip and upload the app so you could try for yourself 
tic-tac-toe.txt (79.2 MB)
renamed from .zip to .txt in cause of restrictions of upload 
Hi,
Did you manage to find a solution? I have similar issues.
Thanks
Do you have the "homepage": "." in your package.json of the React App?
See the example here: Bitbucket

Yes, but I still see the same behavior. Does the “name” of the json packages make any difference?
Thanks
Hi @MatteoGubelliniSoftC , name won’t make a difference. have you went into static/hello-world and run npm run build before deploying?
Hi, yes, all to the books.
Strange behaviour, it’s still trying to use the tunnel, even when it’s off. As soon as I reactivate the tunnel, the queues start running again.
Please note that the part with the issue is UI kit, not custom UI.
So it seems I was making too many calls inside the queue, ref. https://developer.atlassian.com/platform/forge/platform-quotas-and-limits/#async-events-limits
Strangely I was not getting any error though.
