Installing Jinja2 from packagecontrol will pull a different package than before, see https://github.com/wbond/package_control_channel/pull/8415 . The new package uses text.jinja as its scope instead of the previous source.jinja2, which is referenced by this package. Thus, the default advice to install Jinja2 package is no longer valid. I tried just changing to the new scope, but that broke YAML highlighting. Therefore, in order to get Jinja highlighting again without much hassle it's probably necessary to install the old one manually (https://github.com/kudago/jinja2-tmbundle).
