Scope
The issue affects any application seeking to interact with a Google account.
Description
I use microG currently on two devices, and on both find the same behavior not as desired.
When an application attempts contact with a Google account, microG produces a popup overlay entitled "Allow to sign you in to ".
The options available are "Cancel" and "Allow and share".
In most cases, after is selected "Cancel", the application will proceed, without any further such prompts, and presumably without any interaction with the Google account.
However, if interaction with the Google account is desired, then it would be necessary to choose "Allow and share". However, choosing the particular option results in the same prompt being reproduced immediately. Always selecting "Allow and share" would produce an infinite loop. Selecting "cancel" is necessary to exit the loop.
Steps to reproduce
Unfortunately, I have never observed correct behavior for the particular aspect of microG.
As such, I cannot provide any steps that specifically would reproduce the issue.
Expected behavior
After selecting "Allow and share", the application proceeds normally, now having access to the Google account.
Screenshots
See below for screen captures.
System
The AOSP version is 16.
The system image is Lineage OS 23.2, from a build distributed by the microG project (i.e. Lineage for microG).
The device is a Pixel 4.
