Trouble upgrading Metabase on Heroku

Were you able to upgrade metabase on heroku?
Every time i go through the instructions, it tells me to use metabase-deploy which hasn’t been updated in months. I have added metabase-buildpack as well.
Everytime I run
git push -f heroku master
It says “Everything up-to-date” but it did not upgrade.
Any help would be great!
