App installed, without hitting the authentication route

I’ve observed this scenario twice in our app: the app hits the install route and we receive the logs. After a few seconds, it hits the install route again, logs are generated again, and the app is redirected to the install flow once more.

However, in the App Dashboard it shows the app as installed, while in our database and logs there is no hit on the authentication callback route.

Has this occurred only in our app, or is anyone else experiencing the same behavior?
