I got an Email from Degiro. It states that according to new PRIIP regulations certain Funds and ETFs are now required to have a KID in all local languages. The email seems to have been triggered by some positions in my Swiss account. The topic is also discussed on Reddit.
Degiro states you can check that for a products in its “Documents”-tab on their website. But I found ETFs that do have KIDs in every language on their own website whilst Degiro doesn’t show (have?) any.
Additionally I think they are closing the loophole where you exercise options to get banned ETFs. I can’t find a reference at the moment.
The changes are effective immediately (so yesterday, 16.03.2023).
