Hi there Amplitude Community!
When using Amplitude Web SDKs, it is possible that some users’ events are not ingested into Amplitude due to ad blockers. Currently, we are not able to estimate the percentage of events that do not get ingested as we do not have the data to support it.
While we do not offer official support for circumventing ad-blockers, our Engineering Team has provided a workaround - run a reverse proxy through your own domain. Please note that it is best that this process is done by an Engineer or a Developer as this is a technical workaround.
Details on what a proxy service is and how to use it in this setting can be found here:
Hope this helps!
