The issue has been fixed and players can now perform multi-summons from the Deling City Gateway Raid Box Summon.
Thank you for playing
FINAL FANTASY BRAVE EXVIUS.
We are aware of the issue wherein
players are getting connection error when attempting multi-summon
after Box 5 in Deling City Gateway Raid Box Summon. Single summon
is working as intended.
Rest assured that the team is already investigating the issue.
We humbly apologize for any inconvenience caused.
Thank you very much for your understanding.
- The FINAL FANTASY BRAVE EXVIUS Team
