When PostFinance added quarterly fees to their 2nd pillar pension accounts, I decided to move mine to Stiftung Auffangeinrichtung BVG
https://web.aeis.ch/ from the recommendations here. Very late getting around to it, so the account was only opened up November last year... but it's now late April and they have still not provided the account statement for 2020 for my taxes.
I have contacted them via their website but will have to find some time to call them soon. I'm located in Canada, so a bit far and the Google reviews I'm seeing for this Stiftung now have me worried what I have done with my pension.

It's going to be a little while until I'm back in Switzerland and can yell at them in person.
Is anyone else still waiting for this info for their taxes? I'm annoyed. I already have the PostFinance info since ages and just waiting on this in order to do my American taxes for 2020.
