[Fiesta Texas] Does Bugs' White Water Rapids stop operating at the same time every day?

We've been to Fiesta Texas three days this week (all day Tues & Wed and a half day Thurs). Bugs' White Water Rapids was down every time we checked.

While at the riverwalk this morning (Thurs) the app showed it was open, but it was "temporarily closed" all day after 2PM.

That, and Thunder Rapids seems to operate whenever. Closed yesterday but open today (didn't bring proper swim attire so we didn't try it).
