iOS - Not full screen (F7 - v5)

On iOS 13.0 and higher - Bar at the bottom of the screen. (Not full screen)
On android - everything is fine.
On iOS 10.3 - everything is fine.

This can be seen when you first start the application.
If collapsed and reopened, everything is fine.
If you close the application, then start it - again the strip.

where to look for a solution?

Use developer tools in the browser to inspect the space to see what it is. Alternatively, use framework7cli. It’s really easy and the app displays correctly on the latest ios.

The solution was to remove the “viewport-fit = cover” from index.html (meta)
