Problem-related to user experience? Users currently face uncertainty after clicking a button, as there is no immediate feedback or indication that their input has been received. This lack of visual feedback may lead to confusion or frustration.

A solution to the problem. Implement a visual indicator, such as a loading spinner or a brief status message, that appears after the user clicks a button. This indicator should communicate to the user that their input is being processed or that the action is being completed, providing a more seamless and informed user experience.

Cal-feature

Alternatives I've considered: A simple loading spinner that appears immediately after a button click. A brief status message (e.g., "Processing..." or "Please wait...") to inform the user about ongoing activity.

Additional context The "I'll connect my calendar later" & "Set Up later" buttons need the same improvement.
