This is not accurate. No one lost their coins. What actually happened was that some users noticed the flaw in their mobile app's code. This could potentially affect the small number of users who set up their Tangem using SEED ^{i.e. preferred to have not seedless wallet} , and contacted support within one week of setup without carefully reading the automatically generated relevant  message content in the app.


  By that logic  all software developers would be considered amateurs. Even Linus Torvalds would be since Linux has had plenty of bugs  some of which went unnoticed for decades. No software is completely bug free. Show me the complex software that has zero bugs.
