I play on an Android device with the version 11. Sometimes when i open relics an error appears that i do not fully remember but it started with "Beep boop.", i think it showed somekind of connection error and doesn't let me open the relic. When i exit the game and open it back again the relic is completely gone and i have no new items. This mostly happens with Premiere relics for me, though it has also happened with other relics, just less often.
