as mentioned in the heading i always get a message "Access to the path is denied" when i am trying to load a pdf file inside SkyDemon.

It happens when i am trying to load aerodrome charts or approach charts (eg. DFS Charts, standart SkyDemon Plates or the help file).

I only can find a file called "SkyDemonOutput.pdf" inside my main directory which can be opened outside of SD with the installed PDF reader.

Tablet model is Samsung Tab 3 8" with the latest system updates, SD version is 3.12.11.22754.

i am also using a Samsung Tab A 10.1 where this problem does not occurs: i can open PDF files there and they are saved on the tablet like 339991.pdf for an approach chart or 339990.pdf for an aerodrome chart and so on, so every airport has its own numbers.

Trying to install another pdf reader doesnt fix the problem, always getting the message.

Any idea what i can do to get it work right?

Thanks in advance

Model: SM-T311

Android Version: 4.4.2

EDIT: i downloaded the Beta from today and it works great, thanks ! 

The only thing to mention is: every file is named as "SkyDemonOutput.pdf" - on my SM-T585 with Android Version 8.1.0 every file is named with numbers (as mentioned above)
