That's the good thing about Tap for me. It rarely happens with Tap. With FC surveys it happens quite frequently, same thing with MyThoughtCounts. But it's only ever happened on Tap two or three times in the years I've been using it.
My concern is that Tap won't get fixed anytime soon because of the pandemic. However, the Tap DQ bonuses crediting on FC has been broken before. And each time I've been ready to give up and move on they get them back to crediting on FC. So, I'm trying to remain hopeful.
