AAC file album name problem

[Radio_Mayapur]

If I put two AAC files in a folder and open that folder in Mp3tag, then type the Album name for only one of the two, then click the Save icon, in current version of Win 11 Media Player, the AAC file with the Album name changed in Mp3tag will not play and gives the error that the file type is unsupported, incorrect or corrupted. The AAC file, with no changes, is also saved at the same time and plays perfectly in Media Player. Is this as designed?

[X] AAC tag not recognized by mobile

I usually convert my mp3 to aac using NeroAAC before transferring them to my mobile. The tags written with Mp3Tag are not recognized by my mobile(nokia). I used Abander tag and it's working fine. The thing to note that was Abander displayed ID3v2 tags. While Mp3Tag used APEv2. So maybe Mp3Tag doesn't allow ID3v2 tags for aac files that could be the problem.. Tested latest beta 2.45b and still same... Also reading tags from mobile takes considerably more time than with other tag editors.... […

In general: AAC is best wrapped in an MP4 container.
