Thanks, yes there is a big chunk of the build log missing, but that is OK.
I can see that p4a is not building Pillow.
I saw another user last week, who had followed the same YouTube example as you, and had the same two issues.
In that case after fixing the install issue, I replicated the issue, and the user confirmed, we fixed the second issue
with p4a.branch=master this is the default.
(nobody should use the in development version, but it seems that YouTube video misleads)
I demonstrated the fix using the release Buildozer. Perhaps there is an interaction?
So try: uninstall the development version of Buildozer and install the release version
And please double check that the installed apk is really your latest build.
