Won’t let me get the daily rewards done

I tried to do watch an ad to finish today’s tasks but it refuses to and say I reached the maximum amount of ads available for this reward for some reason and now I can’t do anymore while it lets me get ads for other rewards. How is this even remotely fair? I very much needed to get the daily remwards of today but it just hatepkeeps it from me. I think this is a bug or some issue and I hope it gets fixed.
