When restoring did you make sure to select 2 factor authentication when asked what kind of wallet it was?
Thanks @Abdussamad
When I try to restore the old 2fa wallet, there is no warning or error message, after do that, no send/receive history and no banlace found( in fact there are several BTCs in it)
there are 12 words in the seed of this old wallet, and I am sure seed is right for I just copy and paste them
I forget which version I used to create this wallet, but it is in near Jan 2017, 9 months ago I created it.
Are the addresses on the addresses tab familiar ones?
