After doing a search on the forum, i wasn't able to find out some clear info about this issue, so I will ask some clear Yes and No questions.
1. Is it true that the current xenforo version uses the OLD analytics code (the one before Universal)?
2. Is it true that if i want to use the universal analytics I must insert it's code manually (by editing some file) in xenforo?
3. Can I also do the insertion by some add-on? Is https://xenforo.com/community/resources/better-analytics.2288/ a good option for that?
4. Are the any other add-ons that do the same thing?
Thanks a lot for the answers!
