Advertisement history is gone

Hello.
I've got multiple accounts with an advertisement history in past (mostly ~pre-2015). I refer to clicks, cost, impressions...
Just today in the morning everything was fine, but now those stats are entirely erised. I see nothing.
There is no connection between these accounts.
Is anyone else experiencing this? Or it's just me? I hope it's a glitch.

I think it’s just a temporary glitch on their side, maybe some server or reporting issue. Give it a day and check again, it usually fixes itself.

It is still not fixed.
All stats before 2014 seem to have been erased on all accounts? Does anyone else experience this?

It’s probably a bug, and your old ad data should come back soon, or you can ask support to check.

It is 100% a bug and you should contact their support to explain to them the situation imo

It's still not "fixed" after a month.
Even worse, it's eating up the advertisement history as time passes.
For example, this account has been advertising since 2010. Everything was erased until the first months of 2014.
But now, as days pass, stats get deleted. Like here, 2 days passed so 2 days from the beginning of the 2014 were erased.

There is no sense in contacting support as it has happened to all google ads accounts, not just a couple. I tried for one and they answered with some usual nonsense as to how to reactivate my account as it's canceled.

hey, it really looks like a temporary glitch and i think you should wait a bit and check again and then If it's still missing contact google ads support.
