The testing channel will very often publish “final”. Only commenting as reports like this trigger “why don’t I get it?” from others.
That ‘s a test build :
Don’t know where you get this from, because it’s not offered from any source:
OTA update yesterday. The builds are staggered so not everyone gets it at the same time - I assume to avoid overloading the servers. Interim test builds either have the word “beta” or “RC” in their version info.
Check your Settings → System → Developer options → Connect to /e/OS test channel
Is this enabled?
As far as I know by device not region.

Issue:
Glad to hear that one problem resolved.
Others may wonder “where is my e-4.3?”
This is a declared Testing build.
Edit, to answer reply below. That is, Testing channel, “final”. Warning already given on that thread.

Everything working fine. I enabled ipv6 on my home wifi and it seems to be working properly. Thanks for the update
Yes, I saw that, but now they’ve disappeared again from both the test channel and the official channel. Very strage this 
Oh dear, I just updated my FP6 to 4.3.
Let’s see what the reason is for pulling back the update.
Try a call via Whatsapp or Signal and check if you hear Mickey Mouse.

Download took more than 2h, which is way more than usual for me (via 5G unlimited data / data speed). Installation and reboot was, on an other hand, very fast (few minutes).
I still experiencing the same download issue for Apps in AppLounge, where I’m unable to update the apps via my network provider but only via WiFi.
Edit : I’m able to download a new App, but again, updating an existing app remains impossible.

I can confirm the slow download speeds for both FP3 official and FP6 official. DL speeds seemed to hit a ceiling at 500 kB/s (right now they are reaching 1 MB/s). – In the Updater, these would not be offered at all yet.
Surprisingly, FP3 official is available (see above) before FP3 community, making me wonder if it’s a writing on the wall (the long-announced start of retiring FP3-community?) – which also made me a bit reckless and add another chapter to my 
What wiser ones warned you against adventures. I was able to go from e-4.2-a15-20260816663281-community-FP3 to e-4.3-a15-20260917677554-official-FP3 in one go.
Manual installation of the same file through the /e/ RECOVERY was eventually SUCCESSFUL. To get there, I had to accept a signature verification error.
P.S.: The bootloader on this device is unlocked.
Fairphone | FP6 | FP6 | previously on e-4.2-a16-20260815662938-official-FP6 | not rooted
Update did not show yet in the Updater, but succeeded via local update.
I tried to update but the download got stuck and after canceling the download I don’t see the update anymore in the Updater. Any idea why and how I can download it again?
