I had the same problem, to work properly app need to set proper arguments like "yt-dlp -abcd" and some people had problem with downloading speed, this problem was solved with usage of custom downloader option of yt-dlp, as custom downloader aria2 app was used with options to split downloaded file into 16 chunks downloaded in parallel, also as channels change names of videos you can accidentally download same file multiple times, to avoid that use dedication like fdupes or something, imo you should delve deeper into it and slap some bash script for your personal needs), then recurring cron job to repeat that script when you need it
