How to make YT scanner crawl deeper in the past

[alfonder]

On creating a new item in yt section I defined "keep: 5". But then I realized that it'd be better to have more last episodes. I changed config to "keep: 10" and restarted container. (BTW I don't know if it's possible to apply changed config without restarting). I see in the log, that the option is active:
2023/02/25 15:13:27.212 [INFO] got 15 entries for ОСНОВА, limit to 10
But the rss for that yt channel still contains the last 5 episodes. I guess FM reserves 5 more slots for future videos and doesn't go deeper into the past.
The question is %subj. As if I initially added the channel with "keep: 10" parameter.

the already processed entries won't be added, i.e. setting keep: 10 will work for the future entries only. In other words, eventually it will have 10 items, but you need to wait till 5 more posted on youtube

If you don't care about the current feeds and all you want is to reset to 10 - you can stop the container, remove all var and start it. This will start from the clear state and will download 10 items.

Thank you for the answer. But I don't want to lose the other feeds. I suppose that FM identifies YT feeds by the channel ID, therefore renaming the feed won't help. Is it correct?
