SPACE BAR / HAND TOOL WORKS SOMETIMES & MORE OFTEN IT DOSEN'T !!
WHICH IS VERY ANNOYING....WHATS HAPPENING TO THE ADOBE SOFTWARES..??
SIMILARLY FOR PHOTOSHOP, HALF THE SHORTCUTS ARE FUNCTIONAL AS PER THEIR WHIMS! SINCE THE TIME I HAVE UPGRADED ILLUSTRATOR , IT HAS STOPPED WORKING! IT WORKS AS PER ITS NEED AND WISH.

I have the same issue except it's not working ever.

Same problem happening in my Photoshop and Illustrator. Seems to be intermittent, happening on and off over the last few months. Chrome does not seem to be the problem for me. Any news on this Adobe? As others have said this is a major workflow problem. Mac Mojave with Wacom Intuos Pro.

closing chrome solved this for me, also. Illustrator 2020.

This issue is getting worse. Now the last tool used, remains the selected tool, no matter what keyboard shortcut I attempt to switch to. Even I try to switch tools with the Tool-bar, the tool won't switch, UNTIL I start closing browsers... usually closing Chrome fixes it.

This is why nobody wants to update ever, something is always messed up! Very disappointed because we all spend way too much for this to be happening.

This appears to me to be an Apple OS problem, not an Adobe problem. The same tool stopped working at the same time in Vectorworks, a CAD program I use. I suspect that every app (and there are quite a few) that use this shortcut will find it broken. It is really a drag for me since I spend most of my time in Adobe apps and Vectorworks. This stuff is expensive, more than it used to be, so all of these companies need to work nights and weekends to fix it. But they won't.

Spacebar+command doesn't work for the zoom tool either.

Additionally CMD + SPACEBAR does not invoke the zoom shortcut anymore.

I have the same issue. Will there be an update for a fix?

I quit chrome then restarted photoshop and illustrator (the hand tool stopped working in both applications) and the hand tool is back. Opened chrome again and the hand tool is still working, for now. Maybe this will help someone.

This is a very frustrating bug as this is a MAJOR workflow interruption. It's so ingrained. And these tools are not cheap! The last thing we need is something we're paying 60/month for, messing with our productivity. Clearly this is not an isolated incident, Adobe. Fix it.

MAC High Sierra, Illustrator 2020

The spacebar does not function at all as the 'quick' hand tool. Pressing (H) still works, but the basics (spacebar) does not.

Please fix!

Illustrator has become a complete joke. Adobe have lost the plot. Screen often won't redraw so you are working blind - the pixel grid is STILL not aligned properly and the bugs - OH the never ending list of bugs.. They are clearly prioritising features over quality - reliability and precision. Illustrator CS6 was the last good version - every extra release has been a step back.. Well done Adobe

Sorry for your guys who had no luck fixing it by my solution. I've just shared my experience. Besides, I've faced this issue before (It was about 2 years ago I guess) and that was about Chrome/Adobe as well. So this time I've just tried and got lucky.

As a guess, maybe it is not about Chrome exactly. Maybe it is about some specific web page and technology used on them and may appear while using Safari or Opers as well. Just a guess.

it seems to work and then not work with no pattern. i use it a lot so hope you can find the solution!

This is not working!!!!! Painful

I still have it in 2019. And the Chrome browser is note even launched.

Today all of a sudden I've got this issue. Restarting the Ilustrator did not help, BUT restarting the Chrome browser had magically resolved the problem.
Catalina 10.15.1.
Hope it'll help someone

After the 2020 update the spacebar shortcut sometimes works and sometimes doesn't. Restart didn't improve things. The same thing happens with Photoshop as well.

Same here, and I also turn to you guys to get it fixed soon, as it stops all my work. Does not work in both PS and AI
