They have already updated the community about what's happening and as per their statement the licence is under renewal process due to which they have implemented changes and you don't need to worry about operations and your wallets as they are safe.
You can check out this tweet to read the full information and they have 365/JAZ licence I think which needs renewal each year but check tweet for more details:
Read tweet here There are really people who are easily been shaken up whenever they do see some changes or somethings odd is happening but we know that Rollbit wouldnt really last up for how many years if they would really be
not minding much about their license or something that do talks about legal things.Of course they would really be wary if there would be things not to be in line on which it would be understandable that they would really be needing to renew or process it.Its not really that not necessary that these information would be announced every now and then or on the time it do happens.Its not really that much in concern because these are in default things which needs to be complied and in line when you are running a business including license and everything correlated to it.
