In the Tumblr app, if you hit the search button on your profile a list of every tag you have used in a post will pop up.
Is there a way to delete them?
I deleted all the posts that contained the tags, but the suggestions are still there. I deleted the search bar completely on my PC but it is still there in the app.

The answers is that deleting tag history is not supported.
I also wanted to know if this is possible, so I contacted Tumblr Support to ask them.
For reference, this is the response I got from Dave at Tumblr Community Support;
