Power BI Report Builder - Inconsistent Report Rendering Across Different Environments

We're experiencing inconsistent report rendering behavior for a SSRS/PBIR report (RDLP) across different environments. The report has been functioning correctly for 3 months until recently.

Current Behavior:
1. Power BI Report Builder (Desktop):
- Renders correctly with all expected data
- Shows all 21 pages as designed

2. Customer Browser Access:
- Only shows 4 pages
- Incomplete data rendering

3. Developer Browser Access:
- Shows blank/white page
- No data rendered
-Filters work and are selected correctly

Technical Details:
- Report Type: RDLP (Power BI Report Builder)
- Data Source: Power BI Dataset
- Recent Changes: None on our end
- Duration of Issue: Recently emerged after working correctly for 3 months

Expected Behavior:
All environments should render the complete report (21 pages) with full data, matching the Power BI Report Builder preview.

Impact:
This inconsistency affects our production environment and customer experience. The report is critical for business operations and needs to render consistently across all access methods.

Troubleshooting Steps Taken:
1. Verified data source connectivity
2. Confirmed report settings are identical across environments
3. Validated user permissions and access rights
4. Tested with multiple browsers and users ( IE, Chrome Opera)

5. Affects mutlible reports.

Request:
Please investigate potential service layer changes that might affect report rendering consistency across different access methods.

Could you please provide guidance on:
1. Known service-side changes that might affect rendering, last update date? any breaking changes?
2. Recommended configuration adjustments
3. Any required updates to maintain consistent behavior

I know this is in preview still but customers need this especially moving from on prem to cloud.
