Thank you for sharing this, and we're sorry for not getting back to you sooner.
We understand this isn't what you're expecting. Can you specify when AE is slow? Is it slow when you try to edit a project or a template? We suggest closing the page and clearing your cache before opening a new one. It may be necessary to try with a different browser, such as Google Chrome or Microsoft Edge. Can you please send a screenshot or a screen record so we can see what you're experiencing?
We're here to help and looking forward to hearing from you.
