Hey @Sydney!
Indeed, sounds like you should upgrade to a more recent version of Go to benefit from all the features (availability, but also much more).
Just curious: do you know what release your Go marketplace is based on?
Whoever you hire, make sure that the update is to, at least, v10.0.0. We’ve just published it and it brings lots of behind-the-scene changes to the availability technical setup, so it’s good to move directly to that version as the earlier availability solution (Harmony) has been deprecated.
