The log-in has either already been taken down for "the new era" or it broke earlier today and no one has time to fix it? At least I can't log on to my account for a few hours now

For me the log in being taken off started exactly at 6 pm Finnish time, but I had trouble logging in before that too. I couldn't log in using Opera browser at all, it complained of incorrect password when it was 100% correct. Firefox worked fine.

FF and Safari didn't work for me during the day , the same "check password" .
chrome worked around 17 EET, but didn't try that one earlier.

I got kicked out of the AY app today morning although they promised that I would stay logged in during the service break?

For me no issues with the iOS app. Even the flights booked yesterday evening show up today.

same here on android

Same here, on iOS.

Yeah, iOS works. It even lets you upgrade but with cash only.

I'm Ios and could luckily add the upcoming flight as a guest in the app.

For me iOS app is not working. Got kicked out and can’t log back in. Well, they probably will sort it out next week. Interesting to see how many adios they have fumbled away during the process.

For me the iOS app shows now Avios. Vouchers are still unchanged.

Me too it shows Avios, but the number of Avios still reflects old number of Finnair Points, not the Avios (i.e. 3:2 conversion has not been done).

What is gonna happen to vouchers after the change? Hopefully they are not being removed?

The SH/LH distinction will be removed and they will be converted into "unit" vouchers

Android app here, both Avios and Tier points are accurately updated. Upgrade coupons are still old style.

My points have now been converted - correctly as well.
