Google doesn't like app install interstitials, and it doesn't like sneaky workarounds for things, so it should come as no surprise that it doesn't like sneaky workarounds for app install interstitials.
As an update to its mobile-friendly algorithm in November, Google said pages with an app install interstitial that hide a significant amount of content on the transition from the search result page won’t be considered mobile-friendly.
"Instead of full page interstitials, we recommend that webmasters use more user-friendly formats such as app install banners," Google said at the time. "We hope that this change will make it easier for searchers to see the content of the pages they are looking for."
Some app owners have found a way around this, but what they're doing may not help them for much longer.

According to Google's John Mueller, Google may take manual actions on things like this and may even alter its algorithm to penalize such practices.
