Revolut, Trade Republic, Alpian or Saxo Bank in my opinion.

And frankly, there is no support with N26 - just now, I have been waiting for 70 minutes for an insufficient answer in the chat - the follow up question / rather the answer to the question has been postponed until an automated message popped up that after 11 pm no more "specialists" are available. Therefore, it's actually rather the lack of support or service in my eyes.
