I tried to wait to see if there was a resolve and noticed that I didn't see anyone with this particular issue. I registered a booking page through the bookings app. I went and tried to schedule an appointment as a trial and noticed that after selecting a date and time to book, the additional fields at the base of the page either have no text present or are the same color as the background and cannot be seen. So, if I launch this no one will know what information to place where. Is there some kind of resolve for this? I already tried erasing and re-entering this page, as well as changing the color scheme of the page.
I had the same issue and have just found why. I’m assuming your on Apple device, most Apple devices auto changed to ‘dark mode’ in the update. Turn your device back to light mode and it does the trick.
