Based on your key phrase 'Mp3tag 3.22a download the last version for ios', I've analyzed the text you provided and found the following information:

* There is no mention of an iOS version of Mp3tag 3.22a in the text.

* The latest version of Mp3tag is actually version 3.22b, which was released on September 20, 2023.

* You can download rollbacks of MP3Tag for Windows from Uptodown, but there is no mention of an iOS version.

However, I found that Mp3tag is available as a standalone version and on the Mac App Store. The Mac App Store version costs $19.99, but you can download a seven-day trial version from the official Mp3tag website.

If you're looking for an alternative solution to edit metadata of audio files on your iOS device, I recommend searching for other audio editing apps that are compatible with iOS devices. Some popular options include:

* Audirvana: A music player and file editor that allows you to edit metadata and tags.

* Decibel: A free audio converter and tag editor that supports a variety of file formats.

* TuneMyMusic: A music manager that allows you to edit metadata, tags, and album art.

Please note that these alternatives may not have the same features as Mp3tag, but they can still help you achieve your goal. If you have any further questions or need more assistance, feel free to ask!
