Re: I would like answers on that

yes, but what I can’t understand is that they can’t give technical explanations about it, if it’s a network update, why only blocked deposits? as I said, withdrawal works normally, transfer between wallets too.

If the team itself can't give you an answer so there's no way for us to answer it.
How long they have blocked the deposits?

Around 1,5 month

That's already a long time if they've done that. It's a mystery that neither you and me can't answer if the devs themselves have no clarity why they've done that.
I hope that it will be up soon and devs will come up to answer you.
