I have this same problem, yesterday it worked fine. Today I cannot join. Join button presses but nothing happens. Rebooted iPad, closed apps, restarted, etc. still cannot "join".
Today's activity is spending energy on hard battles. As long as you play hard battles (light or dark), you will get points towards the Guild Activity for the day.
When I press "Go" the game sends me to a hard battle. I can then play it or not.
Alternatively, I could go straight to a hard battle node of my choosing, play that level, and the game automatically adds up the energy I spent on hard battles, regardless of going through the Guild "Go" or if I go directly to a hard battle.
The same should apply for the other activities of other days (light side, GW nodes, Daily Activity, dark side, # PVP battles).
