Iphone app update using different web hosts

I used two different web hosts to deploy my app for this test.

The same app was deployed to both hosts, installed app on iphone, made a minor change and then refresh deployed the app.

On host #1 the app would update immediately after I swiped-up closing the app.

On host #2 the app would only update after I cleared cache in Safari.

Why the difference?

What version of AppStudio are you using?

I’m using the latest version
