Just uploaded build 19 to TestFlight for the Gluon 2021.2 update. Release notes are as following (with a heavy heart):

Hey ya’ll, it’s Vincent with another episode of "Let’s do an app update", in the development studio on Planet Earth, targeting your upper body with grey matter strength and finger agility.

Due to popular demand, I have tried adding timeline sync. However, I have failed for now. In shocking news, I have removed this temporarily as I work on it more in subsequent builds. It won’t ship with this update though — which makes me real sad not to get this to you…. But it also made me really sad with the slight corner I painted myself into. I may add it as an "experimental" feature AS IS.

Fear not, I have some other goodies before I ship this update to the public.
In this release, as you may have guessed, I have removed the troublesome timeline sync — the app should feel just like a snappier Safari.

I have also updated the tab bar with different icons. Please tell me how you feel about them. They’re more subtle than the last and mix a few things.

Let me know your thoughts — except about timeline sync.

That’s it fam. Remember to keep updating. Close your rings.
