After openening a document to sign on Adobe Acrobat and clicking on Fill&Sign, my signatures that I created long ago and have used many times were just gone, the only options are to create new ones. I created the existing ones on another laptop long ago for which I had a pen and could create good looking signatures, I don't have those tools anymore.

I tried restarting the app which had the same issue. Then I signed out of my Adobe account and logged back in (within the Adobe Acrobat app) and that made no difference. I logged in online on a browser and there is also no signatures, I tried another laptop with no success.

I believe the signatures should have been stored in the cloud because I moved between laptops and Adobe remembered my signatures.

Now they are just gone.
