Catching an angel fish was the last step of this week's quests for me and you said it was also the last step for you. I got credit for it when I stopped fishing, even though I didn't actually catch an angel fish, and that ended the week's quests so I don't have a plumbob any longer. It sounds like the same thing happened to you. My guess is that fishing in the Crawdad Quarter neighborhood of Willow Creek was the actual requirement.
The Reaper's Rewards panel in my game shows that I completed all quests for week 3, so I expect the quests for week 4 to show up on schedule. I think you should expect that, too, unless your Reaper's Rewards panel says you haven't finished.
I doubt that The Sims 4 bug fix team is only working on PC fixes for these problems. The last update (Oct 1) included fixes for PC, Mac, and Consoles and I expect that will continue to be the case.
Happy Simming to you, also, and I hope you don't let this spoil your fun in the rest of the game.
