But for some reason my amount instead of 428 334 346 was 22 166 402 and now its even less . And there was no transactions. I have reimported wallet but my account become even less.
There is no problem with the app. This token has an elastic supply.
Elastic supply tokens have a changing circulating supply. The idea is that instead of price volatility, what changes is the token supply through events called rebases.
Simple explanation. Price goes up, less tokens. Price goes down, more tokens.
I suggest you to read and understand on tokenomics of any project before investing.
For more info contact token project support for clarification.
