Epic win-Internet problem


Sep 1, 2021
Hello everyone.
Hello. I started playing online casino 1 year ago. I play mostly at Lottoland. I always play for small amounts (up to 1 euro). Everything went well until yesterday. I played the game Christmas tree (yggdrasil). After a few minutes of playing, I hit free spins. I hit an incredible 3700eur (0.80 € bet). After the add-on (big, amazing, epic win), the game froze and threw me out of the app. When I logged in to the app again, it didn’t show me that win anymore. What can I do? Is it perhaps the practice of the casinos to deliberately freeze the app in such a win?
