Just submitted the revisions for the first article of my PhD studies and realised after I pressed submit that I uploaded the old figure instead of the updated one, which now does not match the text. Have tried contacting the editor 6+ times but have received no reply and now the status has changed to "in review". Will it be rejected for this? I am both frustrated at myself for not noticing and the editor for not replying to any of my emails in the past week before sending it back to the reviewers. Any experience with this?

I don't think it will be rejected for that reason. If the reviewers notice it they will just put it as feedback.

You can change it when it gets accepted.

I got a reply. They were super nice about it and amended my figure. Won't make that mistake again but good to know it won't be rejected, I stupidly googled it and saw others saying their paper was rejected for minor errors etc. Thank you!

It can take a really long time for them to reply, especially as there is no withdraw option in the system itself (you have to request to withdraw it).

This happened to me, only I had submitted revisions, and then a mentor who finally contacted me after like 3 weeks offered to review my revision before resubmitting. So I had to resubmit the new draft, but the admin person was really good about it and let me just email it to him.

Oh that must have delayed the process a bit, hope it was worth it. Once I saw someone had been assigned to the article I sent them the corrected figure via email and they were nice enough to simply replace the old one.
