I am attempting to deposit DAI into ALCHEMIX Vault. I have linked my MetaMask account and it shows my balance on the ALCHEMIX site but when I select deposit it comes up with MetaMask notification about editing permission but the confirm button is not functioning. It has on the ALCHEMIX page another notification box that says Approving DAI. I allowed this to be open for 30 min or more but has not cleared or allowed me to confirm. Is this normal? Potential problems that I can work? Note I am not trying to deposit my entire balance. Any help or thoughts would be appreciated. Ty
