Toon Boom requires internet connection???

I noticed the trial version of toon boom requires an internet connection - otherwise the program won’t open and work.

Does the same thing happen when the full version is purchased? Or must we have internet connection as well?

once you buy toon boom it is activated online and it stays activated even offline, unless you uninstall it and reinstall you may need to go online again to activated again

You need internet access to download the trial version and key from TB. this is one-time only.
