⚠️ Known Issues

1. Pre-Existing Build Errors

Issue: CosmosDB-related compilation errors in shared infrastructure

• File: RentifyNow.Common.Infrastructure/CosmosDb/CosmosDbExtensions.cs

• Solution: Add Microsoft.Azure.Cosmos package or disable CosmosDB features

Issue: ApplicationInsights trackEvent method missing

• File: conversion-tracking.service.ts
• Error: Property 'trackEvent' does not exist
• Impact: None on floor plan feature - analytics tracking issue
• Solution: Update ApplicationInsights service implementation
