Hi

I am using max modal. The issue happens when there is another modal inside one then the max modal will down

Are there anyone encountering this issue. How to fix it?

We’re seeing the same behavior on our side.

When using a ui-modal (max) for the quiz builder, opening a second modal (preview/media picker) causes the parent max modal to disappear/collapse. In our case, the child modal can still appear, but the builder host/layer gets out of sync and leaves a blocked overlay state.

Important context: we only started receiving reports about this around 2–3 hours ago. We hadn’t changed this modal flow in our app, so this strongly suggests a recent change in the ui-modal / modal stacking behavior.

From debugging, it looks related to nested modal stack behavior in Shopify Admin rather than app-specific business logic.

Would be great to know if Shopify can confirm:

  1. Whether nested modals inside a max modal are still supported
  2. If there was a recent behavior change in modal stacking/hide handling
  3. Recommended pattern for opening secondary dialogs (preview/media picker) from inside a max modal

Happy to share more reproduction details if helpful.

Hi everyone,

We are experiencing the exact same issue starting today.

Our flow uses a ui-modal with variant="max" as the parent container. When we attempt to open a secondary modal (for example, a picker/preview dialog) from inside the max modal:

  • The child modal opens.

  • The parent max modal unexpectedly closes or becomes unmounted.

  • The overlay state becomes inconsistent.

  • We did not change any modal logic in our app.

This behavior was working correctly before today, which strongly suggests a recent platform change or regression in modal stacking behavior.

Could the Shopify team please confirm:

  1. Is nested modal behavior still officially supported?

  2. Has there been a recent change in ui-modal or max modal handling?

  3. Is there now a recommended pattern for opening secondary dialogs from within a max modal?

At the moment, this is blocking our production workflow since our UX depends on modal stacking.

Would appreciate clarification or confirmation if this is a known issue.

Thanks

if you use polaris react, you can use Modal of it inside a max modal

We’re looking into this now. We’ll post back when we have a fix for this.

Hi @Fio,

First off, thank you for taking ownership of this and leading the fix.

We’ve been getting a steady stream of merchant complaints. Our quiz builder relies on max modal with secondary dialogs, and the nested modal regression has broken core workflows for our users.

We’re pointing merchants to this thread, but “it’s a platform bug” isn’t a great answer when their tools stop working.

Is there an estimated timeframe for the fix or any possibility of rolling back the change? Would really help to have some visibility so we can set expectations with our merchants.

Thanks!

Hey @revenuehunt We’re terribly sorry about this. The fix was meant to go out today, but we had some set backs. We’ll aim to have it out in the next day

We are also experiencing the same issue.

Our app relies on multiple dialogs inside a variant="max" modal for several workflows. This setup had been working reliably for a long time, and we did not deploy any changes related to modal handling.

However, starting around March 3, opening a secondary modal inside the max modal causes the parent modal to collapse or unmount, sometimes leaving the overlay in an inconsistent state. This is breaking real production workflows for merchants.

Since multiple partners are reporting the same behavior at the same time, this strongly points to a platform regression in modal stacking behavior.

We request the Shopify team to acknowledge this issue, take accountability, and prioritize a fix as soon as possible, or provide clear guidance if there has been a change in the supported modal behavior.

Thanks!
