The version check would fail any APM document produced with a different version of APM server compared to the version of the installed APM’s ingest pipeline.
In 8.13.0 the version check in the ingest pipeline was removed.
However, in 8.15.0 APM Server has a different way of managing data streams, that is not aware of the version check present in the ingest pipeline.
Thus, the leftover version check remains and prevents the ingestion of data.

I find this a bit confusing, and the main RC is the lazy rollover bug; how about:

Due to the combination of an internal change in how apm data management assets are set up from 8.15 onwards and a bug in Elasticsearch, related to lazy rollover of data streams, the ingestion pipeline conducting the version check is not removed on upgrade and prevents the ingestion of data.
