This bug applies to MP3tag V 2.32 and V 2.32a.
.M4a files are detected by the program but not handled correctly..
Changing an element of a files tags will randomly erase other elements.
For example changing the title will remove the track number and year.
Changing the track number removes the title.
This applies to all functions in the application such as:
Manually changing tag information for .M4a files in the list or Tag Panel. Using FreeDB to select and change file names automatically. Using any of the Convert menu functions. It applies to changes of multiple or single files.
For many of the functions the results are hit and miss with tag data getting lost at random or simply not getting saved at all.
Change the file extensions to .AAC.
As soon as this is done all of the above symptoms are corrected.
