I'm pleased to inform you that the issue you mentioned was resolved in v27.9, and the current version of Adobe Illustrator, which is version 28.0, also has this option. I recommend updating to the latest version. If you encounter any other issues or have further questions, please don't hesitate to ask.
Anshul Saini - can you please let us all know if Adobe is working on adding the "Apply to All" check box back into Illustrator? The problem that I and many other users are having is when we need to replace a linked image with a NEW image (with a different name). The current method does not allow this to happen with one click (like the "Apply to All" allows) and sometimes I have 200+ images that need relinking. This means that I'd need to click 400+ times for this one file! Please let us know the status of this problem. Thanks.
Thank you for your feedback. The removal of the "Apply to All" checkbox was an intentional change. I understand that this has significantly impacted your workflow. I will pass on your feedback to the product team.
In addition, you can also directly communicate your concerns by upvoting and commenting on this UserVoice suggestion: https://adobe.ly/3W4lcrP. This is the most effective way to convey your message to the product and engineering teams.
Yes, experiencing the exact same issue here. I have a template set up that I routinely use for the same size of card, but the design changes. Up until this newest release, all I had to do was open the template, it would pop up with the message saying the linked file couldn't be found, I could just select the new design I wanted to run 16-up or 20-up on the page, click "Apply to all" and like magic, Illustrator would automatically fill all of those slots. Now I have to MANUALLY click "replace" and then go through a bunch of clicks, x16, to get my template filled.
Could it be that you have several links selected in v27.7 and only one link selected in 27.8.1 ? Apply to all will most likely not show if there is only one link selected or to be updated.
