There’s a Discord and a Telegram https://discord.gg/c74S66su5H https://t.me/instasmashrepo

Well I have android too so I block all shorts with revanced. Maybe she can try YTLite ? https://github.com/dayanch96/YTLite I see on the screenshots there are some yt short settings

I use instaDM. I am not able to see what other people post unless I go to their profile, but default won’t show it anyway most of the time as it will mainly give short content videos so I just removed the feed altogether
