I’ve been a subscriber to humble choice since day 1.
I went back through the last 2 years of bundles (average about 1.5 activations per month) and added games to my account.
Next time I get the urge to buy something “because it’s on sale” I’ll go back and add things I’ve already paid for.
Did you hit the limit? I ended up finally adding all my humble stuff years ago and got blocked because I added to many games. I had to wait a day to add the rest.
