Custom app not working on mobile

[Pratapkarn2186]

Hi All,

I have created a custom app, which works fine on Desktop and web-browser.

When I try to access the same on the Mobile app, it tries to load the app but it looks like it fails and a blank white page appears.

Any suggestion on what is going wrong?

Thanks,

Pratap

@Pratapkarn2186 - Are you developing any Teams app. And what error you are getting on mobile or only blank screen is coming?

Hi @Nivedipa-MSFT, I have created a custom app and in the Personal app I am loading an application from an external system. Things work fine in Desktop but in Mobile, I see loader for a couple of secs then a blank page.

@Pratapkarn2186 - Are you developing any Teams application? If yes how you are loading the application from an external system?

@Nivedipa-MSFT: Issue got resolved, a web application was having some issue with the Safari browser.
