Hi Dmytro,
Thanks for bringing this to our attention. We'll look into this.

Hello, I reported this same issue more than 6 months ago, it is yet to be fixed. Some temporary code based on Java's UUID code you can use if you wish:
std::string Authentication::GenerateNewDeviceId() { std::mt19937 mt(time(0)); unsigned int random[4]; for (int i = 0; i < 4; i++) random[i] = mt(); unsigned char *hex = (unsigned char *)random; hex[6] &= 0x0f; /* clear version */ hex[6] |= 0x40; /* set to version 4 */ hex[8] &= 0x3f; /* clear variant */ hex[8] |= 0x80; /* set to IETF variant */ char out[50]; snprintf(out, 50, "%02x%02x%02x%02x-%02x%02x-%02x%02x-%02x%02x-%02x%02x%02x%02x%02x%02x", hex[0], hex[1], hex[2], hex[3], hex[4], hex[5], hex[6], hex[7], hex[8], hex[9], hex[10], hex[11], hex[12], hex[13], hex[14], hex[15]); return std::string(out); }

Gamesparks relies on this code to retrive UUID needed for device auth request:
On Android 8 (and not Android 7.1 and not Android 9), opening this file fails. Which results in UUID to be set "NO-UUID-SUPPORT-FOR-THIS-PLATFORM".
This leads to ALL users with Android 8 getting SAME UUID, and sharing the same session/saves/leaderboards/etc.
This is NUTS folks, get it together! :(
