aac decoder - file with errors in console (plays fine though) - Telekom 360° Apple HLS stream

If you look at the German Telekom's HLS streams with ffmpeg, then you can see:
The Main stream (2D) can be saved/played just fine.
If you look at one of the 2 360° streams, then ffmpeg's aac decoder errors, because the encoder seems to have used some still unknown features.
I'll leave it as defect though for now, since I can't be sure.
The audio plays fine in VLC and AIMP.
FFmpeg still shows errors when I try to copy again, after downloading and saving. (I haven't tested reencoding, yet)
The URLs might change till Monday, but you can get the most up-to-date URL at:
(Inspect the page with your browser and use the network tab to get the m3u8 address)
ffmpeg -i "https://streaming-magenta-music-360.akamaized.net/hls/live/573873/mm360_vr1/index.m3u8" -map 0:p:3 -c copy .\file.mp4
ffmpeg -i "https://streaming-magenta-music-360.akamaized.net/hls/live/573874/mm360_vr2/index.m3u8" -map 0:p:3 -c copy file.mp4
I'll attach the files and the (verbose) console logs.
Hopefully, they will help you in getting ffmpeg to support these kind of aac streams in the future :)
The errors I'm seeing:
[adts @ 0000026004067040] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 34080 >= 34080
[mpegts @ 000001da3ba5d280] AAC bitstream not in ADTS format and extradata missing
[mp4 @ 000001df2d2cb600] aac bitstream error
in-case my attached aac streams are faulty (because ffmpeg doesn't support them, yet), then you still have some time to save some yourself/test on the live streams :)
