Is Play Console bugging out? Huge drop in "Total Installs" despite consistent growth 📉

Hi everyone,

I'm the developer of Miku Wallpapers Live, and I recently encountered a confusing issue with my Google Play Console stats.

As you can see in the screenshot, my app has been growing steadily. The "Active devices" metric is up by 42% (reaching ~1k average), and "User acquisitions" are consistently green. However, looking at the "Total installs" chart, it reached a peak of around 4.5k and then suddenly shows a massive vertical drop-off to nearly zero in the last day shown (Feb 6).

Given that my "User loss" (uninstalls) hasn't spiked and my daily downloads are stable, this makes no mathematical sense. It looks like a reporting glitch or a data delay on Google's end, but seeing that number plummet is definitely alarming.

Has anyone else experienced this kind of "phantom drop" in their Total Installs reporting recently? Is this just a common Play Console bug?

Any insights would be appreciated!
