No transcription available for some phone call recordings and will not complete transcribing

iOS - I don't have any option to share the call recording to Voice Memos in the share sheet. I also can't add Voice Memos as a sharing destination either.

macOS - I can't drop the Call Recording into Voice Memos on my version of macOS. So these possible workarounds are not accessible to me.

Apple told me that they have received numerous similar complaints and their engineers are supposedly working to fix this issue in a future update (unable to transcribe longer call recordings of around one hour).

I thought that if I was able to upload the audio file to a different transcription service, then that could be a work around. Unfortunately, I have discovered that sharing the audio file from a phone call recording in Notes from my iPhone or iPad does not work. There are options there to save the audio file to “Files” or to share the audio file to an app or device or to copy the audio file. However, after multiple attempts at all of these methods to save, share or a copy the audio file from a phone call recording in Notes, none of the my attempts have succeeded. It does show that it is “processing” the audio file, preparing it to share or save, but after that nothing happens, there is no result. So unfortunately, I have not found a work around using another transcription method. I might post this as a separate issue.

I did post this as a separate issue but it seems to be related. The problem seems to arise from relatively larger audio files (associated with call recordings of 45-60 minutes or longer)  - they cannot be transcribed and cannot be saved, shared or copied either...
