I faced the same issue just recently when I recorded a ton of thoughts on my Android phone and wanted to play and transcribe them on my iPad. The Android recordings just wouldn’t play on iOS 😡
However, I figured out a workaround that fixed the problem for now:
- login to evernote web
- open your note with the voice recording
- download the recording in the browser
- I had to convert the Android sound format to M4A to make it compatible with iOS
- add the (converted) file to your note
after this, I was able to finally play the recording on my iPad
