MX15.x firmware has disappeared

[cmr]

I can no longer see the MX15.x release firmware train, can anyone else see it?!?

Yup, gone from the first Org I checked. It doesn't show as a beta anymore, but it was in the dropdown in the dialogue when I actually selected a network for upgrade... But only the version I had on another network in that Org, not the latest beta.

Same here. For me it was 15.22 especially, but it looks like the whole 15.x train is affected.

Wassup, Meraki?!

I can confirm it is no longer there.
Odd thing is that I still have some MX's on 15.22. I guess I should roll back.

Perhaps they found a major issue and then realised it applied to previous versions so pulled the lot until it can be fixed?

Gone for me as well.

Support confirmed that there is an issue that seems to only affect certain configurations but they didn't respond when I asked for more information...
