A. This issue may be caused by a temporary glitch. Try closing the app completely and then reopening it. To do this, double-tap the home button (or swipe up from the bottom on newer iPhones) to view all open apps, then swipe Snowbunny off the screen to close it. Reopen the app and check if the search bar reappears.

B. If the search bar continues to disappear, check for any updates to the app in the App Store. Sometimes, bugs are fixed in newer versions. If an update is available, install it and see if the issue persists.
