I took this screenshot in the morning.
11 minutes later I used the free summon. The timer then started counting down from 22h 59m.
After that I updated the game. 5 hours later it shows like this:
The timer is gone.
It might (or might not) have something to do with this (after I press Daily Summon):
As the above screenshot shows, I’m collecting the daily tokens from loot, chests, etc. to use them later.
It worked fine before the update.
