I have been using Mobile steam app and got authenticated since January, after the new updates on system "March 9", I am getting trade holds for 15 days, but I knew I am already mobile authenticated since Jan. On march 10 or 11, I tried to remove and re-authenticated on steam app, guessing i need to ,because of the update. After weeks and up to now, I am still getting trade hold for 15 days.
I looked on forums and reddit about this.
I got this. "activate both options "Trade confirmations" and "Community market confirmations".
but I don't have this options on my privacy settings both on my Chrome browser, steam client and steam app. I can't find anything about this.
I confirm sell listings and trades on steam mobile app.

The first thing you need to do is verify that indeed you have Steam Guard (Mobile Authenticator) enabled by clicking on your name then "Account Details" and scrolling to "Account Security".
It should look something like this:
This means that your Mobile Authenticator is correctly activated.
However to prevent trade holds you need to have the Mobile Authenticator active for 7 days straight. Since you mentioned removing your Mobile Authenticator on March the 10th or 11th then you should have your trade holds removed March the 17th or 18th.
Additionally keep in mind that it's relatively easy to remove your Mobile Authenticator on the App itself. I've actually accidentally removed it once by logging out of the App.
