In the review process or approval workflow of Autodesk Docs, every time the reviewer receives an email using mobile device about an action item, clicking the button leads to the mobile web browser. The problem is that the reviewer couldn't provide markups in the file. The markup tools show up. However, they couldn't be placed on the pdf. Tapping anywhere just selects the whole page. Also, when doing hold and drag, it just pans the page. This issue occurs both on Android and iOS. Additionally, this workflow works fine in BIM 360. The problem is only encountered in ACC.
