How to fix Apocalymon Wall Dungeon Bug in Digimon UP
In Digimon UP, joins the Apocalymon Dungeon is one of the primary sources of DigiPlates you can find in the game, so it's important to raise your SP Support Digimon Base level and unlock more battle buddies to help you in battle.
The problem is that most players experience the “joining bug” or “Matchmaking Bug” which freezes the screen when players try to join.
The first possible solution is to click the “Try” button and then wait for about 2 minutes without touching the screen for the game to load.
If this doesn't work, you can also press and hold the button for about 20 to 35 seconds to see if it works.
If the problem persists, try clear the cache. You can do that by following these steps:
-
Return to Digimon UP Loading Menu
-
Click on the “Menu” icon in the lower right corner.
-
When the new tab opens, select Clear cache
-
Select “Yes” (don't worry, this won't delete your progress)
-
Wait for the process to complete and then reload the game
-
The game will download important files again
-
Join the game and see if the problem has been fixed
If the problem persists, try a hard reset by uninstalling the app and re-downloading it from the App Store. Sometimes this is the only choice left as the files may have been corrupted and cannot be fixed by simply clearing the cache.
Since save files are stored on the server and associated with your email account, this means you won't lose any progress with this method either.
