Hi @yakupdr,
Thanks for the response.
From the looks of it, it seems like the language file corrupted, which leads to the continuous loop image.
If you have not performed any editing or unsaved changes to your documents, then try changing the application cache and data, and try again.
To do so, go to your device's settings > Apps > Acrobat > then delete app cache and data > launch the app again > log in > try the process again.
Let us know how it goes.
I found the reason. Pover save mode caused that problem. Now the mode off
and the option works very well.
Thank you for effort.
