Why is Google search not showing my previous searches?

[Android Central Question]

Several days ago I deleted all my web and app activity and now after I search on the google search it doesn't seem to show that past search. The issue is even affecting search engine on YouTube. Although every now and then it will show my past searches for a small amount of time and then it will disappear. I have checked my web and app activity and the boxes are checked. I have done everything I can to resolve this issue and nothing works. I don't know if it's a bug or glitch but I only have one option left and that is to wait and see if the next update for the Google app fixes this problem. If anyone has any suggestions as to how to fix this problem please let me know.
