Joined the Delta Ring, but I wasn’t able to access F2P games and Party features. Is this a...

Not all Insiders have access to not requiring gold for f2p games at the moment.Only Alpha/Alpha skip ahead & Beta rings are testing it.If you are not in any of those rings then you will still need a gold sub at the moment.

I have access im in the delta lvl and it talks about us testing it but it will not work on my Xbox and I’m on the current update for delta and I see the I have a Xbox network id

To join just download the insider's app on your Xbox open it go to settings and join whichever ring you are able to. You may not be able to join beta ring until you have been a member for something like three months so you may have to join delta temporarily.

I am currently trying Delta ring. I will report here if it helps with crashing in late game.

UPDATE:

I was able to finish the game that was constantly crashing after updating to Delta ring release Xbox Insider Release Notes - Delta (2208.220715-2200) - Xbox Wire

If Omega ring has same fixes, then hopefully everyone will get this fix soon.

I will continue testing with Delta ring with all addons enabled (currently have extra civs disabled) with new game on huge map.

Hello

You need to work on your XP within the Insider Hub App, to be able to gain access to Delta and Beta rings. You do this by completing the missions that appear from time to time in the App. Alpha is invite only from the development team, for those in Beta
and sometimes Delta rings that have shown they can file accurate reports on bugs and issues.

If you are in the insider preview, I would suggest joining in on the forums here Insider
Forum

That feature is only available to Alpha,Alpha skip aheads & Beta Insiders at the moment.

As you are in the Delta ring you will still need gold to play any games online.
