In your comment on Google Play, you said that the player supports cue. However, this is not true. Here’s what your player and FuBar interfaces look like. To speed up testing, I only indexed one artist’s folder, which contains high-resolution FLAC rip.

The forum engine is awful and works terribly on smartphones! Once you enter edit mode, you can’t exit it. All this instead of organizing support on GitHub, which was created specifically for this purpose. It all gives the impression of a careless student. In my previous post, instead of FuBar, I meant foobar2000.
You mean my answer to your bad rating 
Anyway yes it’s supported in library mode, and thanks to the logs I can confirm that yes there’s a problem with detection.
Probably due to Cyrillic. Can you upload the cue file to https://upload.symfonium.app (And eventually the flac too) so I can reproduce ?
And yes you can close the edit and change it’s size, and this allows a lot more things than github with full control and privacy for the users, something important to Symfonium users …
Well, you respond quickly to negative feedback related to problems. That’s definitely a plus. 
The flac file is large, so downloading and uploading will take a long time. I can give you access to the server (onedrive is duplicated via webdav read-only) if I figure out how to send a private message on this forum 
As written everywhere play store comments are not the proper way to report issue as no information and no way to contact back and 80% of users not using gmail and not getting the message
I answer even faster here
Have you tested WebDav does it work there ? If it does then it’s not really helpful.
And you can’t PM as too new account to avoid spam. As I said user privacy matters. I’ll PM.
So TL;DR; the file is named .fla and so not a music file and so not scanned.
