Acrobat docs and data getting huge without my control

[#1]

 

When i tryed save pdfs(app was 10 gb) to google drive docs and data getting huge without control. Docs reach 20gb but my storage 16gb. I checkd the app  there is no new doc its seems compleatly normal (aprx. 10gb) but storage say acrobat is 20gb. Apple suport wouldnt help. My ipad cant open any app because of this problem. Alos when i try delete something, acrobats docs getting more huge.

I think you should contact Google Drive Support. Also, try to compress PDF files to reduce file size, you can follow this tutorial on Adobe Acrobat.
