Installing AltStore on two separate phones

[coolmarc12]

I’m trying to install AltStore on my iPhone XS Max and my iPhone X. I have it installed already on my iPhone XS max, but when I try to install it on my iPhone X it says that it will not work on my iPhone XS if I install it. I’m using two different Apple IDs. Can someone help me with this?

Just to be sure, you mean the developer Riley on the unc0ver team, correct?
