This video - https://www.youtube.com/watch?v=1p11Prs5PHw has manual and automatic subtitles, the script below download both and compare them, and they are identical (even though it is clear in youtube that the two transcriptions are different)

def set_ydl_opts(auto_or_manual):
    ydl_opts = {
        'ignoreerrors':True,
         'dumpjson': True, ## lower -j
         'skip_download':True,
        'subtitleslangs':['en'],
        'verbose':True,
        'outtmpl':f'test_{auto_or_manual}/%(id)s_%(ext)s'
    }
    if auto_or_manual == 'auto':
        ydl_opts['writeautomaticsub'] = True
        ydl_opts['writesubtitles'] = False
    elif auto_or_manual =='manual':
        ydl_opts['writesubtitles'] = True
        ydl_opts['writeautomaticsub'] = False
    return ydl_opts

#download manual subtitle
auto_or_manual = 'manual'
ydl_opts = set_ydl_opts(auto_or_manual)

Update2: I double checked my download time, and it was hours away from the vid upload time. But I still see this warning in my log
WARNING: Couldn't find automatic captions for Zmr3g83cgJo
Any idea?
PS: I'm 100% sure some vids that are reported without automatic captions, actually have them when I manually double check some time later. It should be expected that the vid was accessed hours after it was uploaded. Maybe a Youtube issue?

Same here, but I can't get subtitle even without manual sub when i run yt-dl in a routine script.
I'm adding verbose option to my script, will be help adding some logs when I run into this again

PS:Running the same script manually works fine, not sure why, I'm sure this works like 3 days before, and all paths are absolute
