Same for me. No issues before this latest title update. Now freezing too frequently. At least once a day, if not more often. Has happened twice in Conquest when trying to enter a battle, leading to wasted energy. Has happened once when trying to enter store even, which is unprecedented.
Have been on both wifi and mobile data, no difference, the freezing issue still occurs.
Have closed all apps and restarted phone, updated everything. Doesn't help.
Samsung s20 fe user. But other non Samsung mobile phones have also reported this issue.
Please acknowledge this on the forums. Some recompense is expected due to the amount of crystals wasted, not to mention botched up fights in TW and Grand Arena.
