I had the same problem until I found that the "blue button" at top right said "complete and continue" when you hovered over it. It would be better is it showed that when you weren't hovering over it. I left and came back the next day before I figured it out. Rather annoying!
Same experience here. Hope this will be fixed, it really is annoying.
Good content on the very first full video on basic pond management. I'd heard most of it before, but always smart to hear reminder that alkalinity is top priority, not pH. Also need for good spawning areas as part of habitat planning.
