Google's Play Services has a funny thing about "backup > reset" or "reset > restore" when it comes to apps and games alike. Did you reset via settings or via recovery?
If via settings, you should have seen a screen saying that your Google account will be used to backup data and will be used as well to restore data after reset. So what happened after reset when you signed again using the same Google account? I bet it never took more than 30 mins on that screen, right?
Now onto some points, how did you re-installed your apps? Is it via the Play Store? or you have a backup apk of those?
On MM, the only way for you to use your SD card for OBB data files is to make it Adoptable but doing so will exclusively make the SD card work only on the phone. And it is not 100% that all OBB data files will be on the SD card and not eat up the Internal storage since app devs would have to adjust to it.
One last thing, on the Internal (Phone storage) there's also an Android folder, what I've done before is to backup the same folder as well as the same one on the SD card, after reset, I transfer back the same Android folder to the Internal which made some (not all) games to not download the OBB files anymore. Haven't done that on AF2 though whether on LL or MM.
