I am writing to submit a formal complaint regarding a significant limitation I am experiencing with Adobe Acrobat on iPhone and iPad, despite being an active paying subscriber on Adobe Pro.

While I can freely annotate, highlight, and write comments on protected PDF files using the desktop version of Acrobat (on both Windows macOS and Android), the iPad version of the same application does not allow me to perform these actions — even on the exact same documents and with the same account.

This discrepancy severely affects my workflow and defeats one of the main reasons I pay for a full Acrobat license: seamless, cross-platform functionality. The current situation suggests that the iPad version does not offer equivalent capabilities to the desktop version, even though they are marketed under the same subscription and price model.

Highlighting text, adding comments, and making handwriting annotations are core functionalities of Adobe Acrobat — and they should work consistently across both the desktop and mobile applications. If these features do not behave the same way with the exact same PDF files and account, it clearly indicates an issue in how the mobile application interprets the file permissions.

Furthermore, considering that both applications are developed by the same company, it makes little sense that the mobile version cannot interpret standard PDF permissions — a fundamental capability that is far from being “rocket science.” This inconsistency undermines the cross-platform experience that customers expect when paying for a full subscription.
