Instagram In App Browser does not show the bottom tabs

This bug happens from an IOS device (Iphone 12) and when the origin is the link in the bio of an instagram account.

Instagram account with link to Ionic web app with tabs:

When I access my web app from the link in the instagram bio, it doesn’t show me the tabs at the bottom of the screen.

how it looks

obtained result :confused:

How to fix (tabs appear again) with user interaction:

  1. Leave the web-app in the background and return to it: the tabs will be displayed
  2. When I touchup on the header: The ion-tab-bar will be revealed

¿Any idea how I could fix this?
