r/Cozmo

I know there's been a thread on this before, but that's not been conclusive.
The Cozmo 2.0 App is not compatible with older cozmos, correct?

Since android appstores no longer have the older App, which APK version and link currently works?
I've been trying both the 3.6.6 and 3.4.3 APK version off of APKpure and I the download either fails, or I get the message that I downloaded an incomplete file.
On AKP Pure, there are
3.4.3 XAPK OBB (492.4 MB) (download keeps failing);
3.4.3 APK (67.3 MB) (haven't tried as I assume incomplete);

3.4.3 APK XAPK (492.4 MB) (download keeps failing);

Even if I download the 400+mB versions.

So can anyone recommend a functional download link and/or working download instructions?
