Dynamic image URLs not rendering in repeating group (Bubble Mobile App Editor Beta)

I have a data type called CountryFlag with a field ImageURL (public direct links).
In a repeating group, I’m trying to show each country’s flag using:
Do a search for CountryFlags:first item’s ImageURL
(constraint: Display = Current cell’s Get Course List course’s location_country)

The URLs are valid and open in browser, but the images do not render in the Mobile App Editor (Beta) preview or run mode.
HTML and Web View elements don’t support dynamic data, so the image element was the correct approach.
Can Bubble confirm if dynamic image sources in repeating groups are currently unsupported in the Mobile App Editor (Beta)?
If so, is there a timeline or workaround planned?

That’s one of the most common use cases, so I highly doubt it slipped through QA testing and simply doesn’t work.

You might be running into a different issue instead. Could you share what your image URLs look like (for example, a sample record from your database)? That’ll help confirm whether it’s a formatting or privacy-related problem.

Also, have you confirmed in Inspect (Beta) that the images have the correct URLs?

Side note: Avoid running a new “Do a search for” inside every single cell. It drains your Workload Units.
