Sometimes Midjourney jobs get stuck.
Midjourney only lets you run 3 jobs at the same time, so you don't want one to be taken up by a useless generation. You cancel by reacting to the generation with the ❌ emoji.
Cancel on desktop:
You can react to any message in Discord. React to the generation you want to cancel with the ❌ emoji. Type :x: to search for the emoji, or copy and paste this: ❌.

Cancel on mobile:
You can press and hold the image you want to cancel (long press), then select apps, then select cancel job.



Can you cancel all jobs?
Unfortunately, there is no way to cancel all ongoing jobs. You have to cancel them one by one.
If you are finding the chat hard to organize, try creating your own Discord server for your personal Midjourney use.
You can add the Midjourney bot to your server and then create channels to organize your generations under different categories.
Midjourney says you have running jobs but you cannot find them
Sometimes you get the "you have reached the maximum allowed number of concurrent jobs
" message but the jobs mentioned do not actually exist.
This is a bug with Midjourney. You can either go into the #member-support
channel in the Midjourney Discord and ask for a reset, restart Discord, or wait a few hours for the issue to resolve itself.
I have jobs that are stuck and won’t complete. (I had one that was stuck, and I started another one and it won’t complete either.) But there is no react button for them! I tried typing :x: in the message bar, but it just sends a big X to the Midjourney bot and the jobs continue processing endlessly. Is there a solution to this?
Hey Mike, I think your best bet is to restart Discord and look for the react button again.
