I wouldn't be surprised. I had and still have so many bank accounts blocked that I am gradually moving all my funds to crypto just to sleep good. CBD.ae for example blocked my account and send me some 10 different forms to fill on 40 pages. When i did, they sent more forms. From what I've heard about WIO, they are reasonably fast in unfreezing the account if provided with POF/KYC docs. With FAB I had to︀ threaten them with a law suit and central bank complain for them to unfreeze the︁ account after few months.
My Nexo experience started with the absence of registration email on︂ my gmail account which seems like a common thing judging by the search results and︃ immediate account freezing after i used protonmail, stated that my residency is UAE using the︄ website from another country. Nexo support still hasn't replied but it is clear they are︅ too dumb even to set up email properly.
All these companies are under stress because︆ there are rouge players who use stolen accounts, nominees for crypto trading and money laundering.︇ It seems like their f***ing problem until it becomes your problem. I personally think DAI︈ is the best option to keep the money nowadays if you don't want to be︉ exposed to Bitcoin fluctuations.
