AVOID. Terrible aftercare.
I used N26 as a travel card then main account after they proved themselves as a decent bank with good international fees and okay app. £100k+ in over a year.  
They closed my (all) UK (residents) accounts due to Brexit licensing issues. 
I then had an accidental refund from an airline due to COVID-19. I was promised it would reach my nominates UK acct within 10 days. Most likely sooner. Two months later and ignored emails from ‘Mark’ numerous excuses about they’re using a new company / having issues / I’m in the refund queue. 
I believe they may go into administration   I will be reporting them to action Fraud once my questions have been answered (several emails asking who the 3rd party company they are alledgely using. No reply). This is a shame as I would have continued using them when I move abroad.
