Lightroom upgrade to V9.3 on Win 11 causes stacks to become ungrouped.

Hi @Ven Seshadri,

Thanks for reporting this. Please update to Lightroom v9.3.1 first, then check whether the stacking issue still persists.

Also, could you help confirm something important:

• Are the stacks actually gone?

• If you go to Photo > Stacking, do you still see stack-related options/indicators?

• Or is the “Ungroup” option greyed out?

• It’s also possible the sort order changed after the update, which can make stacks appear visually expanded/un-grouped even though the stack data still exists.

If the issue continues after updating, please share:

• Your full System Info

* Go to Help > System Info

* Copy & paste it into your reply

• A short screen recording demonstrating the issue

* Especially showing the stacks before/after upgrade or how they appear ungrouped

We're looking forward to hearing back from you.

Best,

Anshul Saini
