I can confirm that we have faced similar issues. E.g. In September the Search impressions were 99% of Browse impressions, whereas in December only 21%.
Has Apple officially admitted this problem or explained why it is? Would be helpful, since we have been making keyword optimization in the Autumn and it is really hard to measure the impact on Search impressions since this.. Furthermore, I would like to get some official explanation in aim to convince our internal stakeholders that this is an technical attribution problem, not a failure in keyword optimization.
This is an article I found regarding this https://asostack.com/aso-monthly-42-october-2019-attribution-issue-in-app-store-connect-release-of-dark-mode-on-the-bd0a80c9d5c3
We have the same issue. Dramatic decrease for search impressions (any keyword changes can not fix it, though we have a lot of top5 positions for high volume keywords) and growth for browse impressions. As app units have approximately the same level, those impression dances causes the enormous growth of CR. It's already 3 months that Search CR keeps growing, due to the fact that Search impressions keep fall down while Search App Units as well as keyword positions stay stable. Normally, if we see the decline of Impressions we also see the decline of App Units, but not in this case. I would be trully happy if we had that kind of CR naturally, but right now this result don't seem right. Hope Apple will pay attention and fix it.
We have also the same issue and face difficulties to measure the impacts of metadata updates. It is indeed a good few months to experience this and we expect that many developers/ marketers are struggling with it. We do appreciate Apple to respond to our concerns as well as fix it shortly. Thank you in advance.
I am facing similar issues with a variety of customers. The issue started after September 16-19th (Switzerland) and a German one is having the issues after October 28th.
I wrote the App Store Support team, but the are not aware of any issues and replied with standard answers. This is very frustrating!
We are facing the same issue in our apps (e.g browse impressions accounted for ~47% in March vs ~81% in December).
I've already contacted Apple Support team but they denied any kind of issue in the attribution, this is preventing us to work on any kind of optimization and also providing wrong info about our app's performance.
We appreciate Apple to respond to our concerns as well as fix the issue.
We have the same issue here. Since 19th September our impressions data from search decreased a lot, but the number of app units from search didn't. In some apps, our search conversion rate increase how we have never seen it before. Something is not right on iTunes Connect.
I would like to know some news about it and when iTunes will fix it.

We're facing the same issues. As seen in the screenshot, it's been 4 months since this is happening, and it clearly correlates with the launch of iOS 13. Hope this gets fixed soon.
