Hi @wxh180,
The legacy cryoSPARC application (liveapp) is still there, it’s just not turned on by default when you run cryosparcm start as of v3.3. You should still be able to start it by running cryosparcm start liveapp. The legacy cryoSPARC application is due to be deprecated in a future cryoSPARC release- is there a reason you’re using it over app (the new, default cryoSPARC Live application hosted on base port + 6)?
