On previous versions of PvZ2, there was a button to create a new profile. The current version (7.0.1) doesn't have it anymore. New profiles can only be created on new installs or if you reinstall. For Android, clearing the cache and data can also trigger this (not sure for iOS devices).
Reinstallation (or clearing cache/data) is not recommended if you don't have your profile sync'ed or backed up to the cloud.
When you have an existing profile and a new profile is created (due to reinstall), the old/existing profile will be sync'ed when connected to the cloud. Basically, the new profile will be untouched when you sync and will now show as a part of the profile selection box together with your existing profile(s). When you sync again, the new profile will be backed up together with the other profile(s). You can repeat this process if you want more profiles. But do this at your own risk.
I hope this helps. Happy planting!
