Does DataUnlocker support product X?

Yes.

DataUnlocker is a product-independent tool, which fixes the underlying common problem (blocking network requests), instead of "fixing" each blocked third-party product like Google Analytics individually. However, there are a few considerations you should be aware of when using DataUnlocker, which effectively means that your third-party product is supported out-of-the-box, but it might have a few inconsistencies when proxied.

Note that because only blocked (proxied) traffic is affected, always safe installing DataUnlocker, and in the worth case scenario you may disable the proxy for a particular third-party service which has artifacts when dealing with proxied requests.
