The work to upgrade the SDK was taken care of in bug 1611770 [Preliminary looks at live data](https://sql.telemetry.mozilla.org/queries/79817/source#198207) suggest that this is working... but not completely. Still getting some `NULL` reasons in there. Gonna file an analysis bug to look into this after we have a couple days' data.

Gonna file an analysis bug to look into this after we have a couple days' data.~ the `NULL`s were from earlier SDKs in use on other channels. When I filtered for the proper SDK version (`AND client_info.telemetry_sdk_build = '37.0.0'`) they go away.
