Thank you for letting me know.
Tested it on both browsers and it didnt happen to me.
I extended all timers to 30+ seconds, hopefully this will fix your problem.
If not i will have to do further research.
Where is the "Claim" button? Nothing happened after I filled in my Xapo address, solved the capcha, and chose the number.
The claim button is called enjoy.
The first hit is a new window the second hit is the claim.
You wil get a message like this.
