When you see "(null)" as a username in the comments, it's likely that the user's account has been suspended, deleted, or they temporarily deactivated their account. It's less likely that they blocked you before you could react, as blocking typically happens in real-time, and the comment would likely disappear or show as "Unavailable" rather than "(null)".

r/Instagram on Reddit: "Null" on everything I send from one platform to another?
December 21, 2024 -

Everything I send to my friends cross-platform is now adding "null" beneath the post. If I want to send a Reddit link, sending it from Reddit itself will yield the null however, copy/pasting the link from Reddit and sending it directly through Instagram does not. Likewise, if I want to send a TikTok video directly through TikTok, it will yield the null but does not when I download the video to my phone and go directly into Instagram to send it there. Any ideas why this might be happening and how I can get rid of the "null" every time I want to send something from my friends directly from one app to another (rather than the workaround)? My app is fully updated to the latest version.
