Box mobile on Android is extremely slow and freeze in offline directory

Looking for solution about my BOX MOBILE on Android. I have all my files made available offline. On the main screen, the left directory (all files) is very slow but works. While the off line directory is working for some sub directory and freezing and/or crashing for some other. So when I look for a file, I may find it in the "all file" directory while in the offline directory it will crash or freeze not showing even the list of files present in the sub directory I try to open. I have 12GB of file made available off line on my cell phone. It's a Z Fold 6. Thanks for help
