Of course, the instructions for doing this will be different depending on whether you're using Android or iOS, but we'll walk you through both scenarios.

Simply go to the subguide (which we will describe below) that applies to your mobile operating system:

1.1. Update the problematic app on Android

Android automatically updates apps, but the timeline in which these actions will take place depends on whether you have mobile data or Wi-Fi or whether you have a habit of keeping your phone in battery saver mode or not.

• Once you are inside the dedicated menu Manage apps and devices, you must touch the tab Manage, then select the filter Updates available and look for the application that is giving you problems.

Since it's clear that the app you're trying to use is making a login request that Google no longer accepts, the solution is clear: either the app needs to be updated to Google's requirements, or the app needs to be moved to an alternative authentication method (such as GTMAppAUth).

However, none of these solutions will be within your reach if you are a regular user. All you can do is report this problem to the app developer using official channels.
