Attempt to call a method that has not been implemented

Hi @Optimistic_Crystal5696

I hope you are doing well, and thanks for reaching out. I'm sorry for the trouble.

To help us look into this, could you please share:

1. Whether you are on Android or iPhone/iPad, your device model and OS version, and the Acrobat Reader app version installed.

2. When the message appears, for example, when the app starts or when you open a PDF, and whether it happens with every PDF or only one.

3. Where the PDF files are stored (for example, on your device, in an email attachment or in cloud storage), and a screenshot of the message (without personal information).

4. Whether anything changed shortly before it started, such as an app update or an OS update.

Once we have these details, we can share the next steps with you.

Additionally for more information about the application please check the help page https://helpx.adobe.com/acrobat/mobile/get-started/faqs.html

Regards,
Amal
