Unable to login after uploading Guild's logo

[Yukkihime]

I'm currently the new leader of our guild and since the previous logo we used is badly rendered on game, I decided to resubmit a brand new, more cleaned logo of our guild. After I submitted the logo, I went offline and later when I tried to reopen the game, it just stuck there at server selection screen, pressing the poring on top right didn't help, cleaning the cache, using different connections, Tap Booster and/or other VPN also didn't help, the only way to fix this is to clear the data and redownload all of it again.
I tried to do the same thing again after managed to get back to game to confirm if it was happening again, and sure enough, I have to completely redownload the game again.
