Your first mustake was not waiting at base until you discovered all the missions. Second was not going for the illegal weapons first. its a giant cache of very good guns, ammo and gear and its only guarded by civilians with low skill and sub par weapons. It really would have set you up for success.
If you mean how to update the game, on mobile iOS you go to the app store, tap on your account icon in the top-right corner, then either tap update all or update Sonic Prime Dash specifically, just like any other app.
@sonicgame5082 I don't have Android, but assuming you have a Netflix subscription, it does look like you can download and play the game on Android devices as well, based on a quick web search: play.google.com/store/apps/details?id=com.netflix.NGP.SonicDash
Wait since when Sonic Prime Dash actually has Prime stages?! I thought it was Prime Dash only for the Prime characters. And since When Infinite is in Sonic Dash?!
Until this update, the only content from Sonic Prime were characters like you said. But now there is a New Yoke City stage. And Infinite was added as a character at some point after I started playing this.
@CARSDIECASTADVENTURES As cool as it sounds it wouldn't make sense for a regular game to have a Prime exclusive while that same game has literally a Prime-themed version of itself.
