This is the first time I'm hearing such claim about coinomi wallet, you should try using mycelium or myether wallet from now on, I might later try out other wallets myself, I don't want to end up losing my funds 
though I have been using coinomi for long and no problem so far
I have never used the mycelium wallet that you have used, and if I may know its function and usage is it the same as other wallet things like coinomi or others? I will wait for your explanation about this, because I just heard about the mycelium wallet. though I have been using coinomi for long and no problem so far
