When i leave a clan & join other clan then i open the eb it show only eb image not any attack options? Tell me the reason
This maybe a delayed reaction give 30 sec then try again. 2nd reason they may have just started eb so look for timer it would be under 15 min
Ok guys if your mage don't work take out battery for about one min. Sometimes server is overloaded and will cause delayed reaction also your devices have a 1 in a billion cycle error rate thats one per second turning your device off for a min will clear this or you can manually clear cache in settings for that app/program
Now on a serious note hope you learned your lesson and read changelogs for the future. Changelog for last update stated very clear "Fixes for Android 5.0 lollipop". You said you have Android 4. That's either IceCreamSandwich, either Jellybean, either KitKat. So supposed to be obvious that last update wasn't for you and you shouldn't update.
Actually, while the fixes were with bugs for Android 5, anyone should have been able to update. The Mage issue is a known one, and will be fixed very soon.
Of course anyone can update. But if the changelog of an update for any app states that the update contains fixed for a phone I don't have its useless to update ans to risk other bugs as long as curent build is a stable one.
