We also migrated to ClickUp (though not from Jira) but while it's better than what we used before, it still feels... I don't know, sluggish. Loaders everywhere, lists are jumping when you scroll. Sometimes I click on a task, the detail modal opens up and there is a noticable delay while the data loads. Typing a / in the description which opens up the command panel or integration panal or whatever it called, freezes everything for like 100ms or more.
