Total Commander

Hi, sorry for my bad English. I use TC 2.91 on my mobile with android 8.1 without problems and on my tvbox A95xf2 with android 9 but in this one I find it difficult to navigate.
Is this a problem of android 9? The new versión 3.0 is for android 9 +?
Can i write the test versión on 2.91 versión?
Thanks

Total Commander does not officially support Android TV.
You can use it, but it's not very comfortable:
1. Use cursor up/down to navigate
2. Use cursor right to switch between panels
3. Use cursor left to select files/folders
4. Long press the OK/ENTER button to open the menu for file operations

The las question: for android 9 , is better the 3.01beta version than 2.91?

Clearly the beta.
