Hi, I have an app that I wrote in oTree 3.4.0. It works fine on my computer, but when I try deploying it to Heroku, I get an error message stating that Python 3.7 is no longer supported and advising me to update to Python 3.9. Does oTree 3 work on Python 3.9? If not, how can I upgrade my app to the latest version? Best, Inbal
