I work on a SaaS app in France. In the past few days we noticed an enormous increase of disputes in our Stripe account, all of them are linked to SEPA payment method (wire).
We used to have 1 every month of so, now we have had around 7 in 2 days.
[EDIT] - I received an email from Stripe a few minutes after I submitted this post on HN. It seems there has been an issue with the management of SEPA payments between end of september and start of october.
[EDIT 2] - I actually received the email before submitting this post, I just did not notice it ;)
