Hi, I'm using Kotlin and trying to update my project with this library.
I include all dependencies, and all the code is the same as in the example.
my apk = 12 mb, but all the time the Toast says "update done", and in the download folder I found an apk with a weight of 133 kb.
Please tell me what I'm doing wrong

upd. for some reason, the download was carried out incorrectly from git hub, after transferring the apk to a custom server, everything worked.
