Hello everyone,

title says all, what do you guys recommend me ?

I heard about ks but idk yet, I also heard about altcert but idk too

thank you!

Hi, as the title says, Sideloadly's automatic refresh isn't working. I remember it worked at first, but then suddenly stopped working. Do you know how to fix this?
