Mobile Version does not show preview OR gives error "invalid path"

Dear All,

First of all let me say that I'm (generally speaking) really pleased with your application.

Second, the server works perfectly (and flawlessly) on PC-based browsers.

But, recently (I'm not able to pin point exactly when) I have started to get problems with the Android App (Filerun Mobile).

a: IF, I login AND accept the privacy statement, THEN I can browse my folders and view the file list. BUT, I cannot preview OR download any file. I get the error "invalid path" on pdf files... and a "loading" message on image files (as examples).

b) IF, I login BUT Do Not accept the privacy statement, THEN I can still browse folders and files, SEE image preview, BUT not Pdf's. BUT I can download any file.

As a final note, All functionalities (preview and download of pdf and images) were Fully working on the mobile app until some time ago. 

Thank you for your help, and hope you can shed some light on this.

Best Regards

AC
