Troubleshooting Event Tracking Issues with Segment and Session Replay

Hi there, Is anyone else facing issue with certain events from the frontend not being sent? We're using Segment, and recently started to use Session Replay. Upon investigation, it looks like for some users not all events are getting sent to segment, primarily the backend events. My hypothesis is that newer browsers are starting to block certain tracking API calls and as a result some events are not being sent. Did anyone else face this issue? How did you solve it? Using a reverse proxy?
