Hi there! I see you're having trouble with the Fresha app getting stuck on an ad. Let's work together to get that resolved.

First, let's try a few simple steps:

1. Force Close the App:
- Swipe up from the bottom of the screen (if your iPhone doesn't have a Home button) or double-click the Home button.
- Find the Fresha app and swipe it off the screen to close it.

2. Restart Your iPhone:
- Press and hold the side button (and the volume up/down button) until you see the slider.
- Slide to power off, then turn your iPhone back on after a few seconds.

3. Check for App Updates:
- Open the App Store, tap on your profile picture in the top right corner, and scroll down to see if there's an update available for Fresha.

After trying those steps, reopen the Fresha app and see if you're still stuck on the ad.

If the problem persists, we can consider reinstalling the app. Would you like me to guide you through that? Let me know how it goes!
