I updated to Craft 3.1 today and when going to the plugin store, I can't install anything (Or 'Try' it) unless I buy the plugin by adding to my cart.
At first I thought this was only happening on the 'Free - $0.00' plugins, but it does it across the whole store.
It seems the Try button has disabled="disabled" on it, so it can't be clicked.
Is there a config setting I'm missing thats new to 3.1 or something similar?
I believe the environment value in the .env file will effect how the plugin store behaves
@clarknelson In which way? It's currently set to dev
This was fixed via eb08ea548e37f00b2ff32b2679eedf0040110c89. We’re going to get a 3.1.1 release out soon with the fix.
After updating to 3.1.1 the "Try" button for paid plugins is still disabled for me.

Using a .local domain and devMode=true
Could manually remove the disabled="disabled" with developer tools and it works...
I am also experiencing this issue now :)
Yeah looks like it’s still broken for plugins with one edition. We’re working on a fix…
OK this is definitely fixed for the next release now :)
You can get the fix early by editing your composer.json file with
"require": {
"craftcms/cms": "dev-develop#2f5f0b90b221540c9de585f21f62d286f00deead as 3.1.1",
"...": "..."
}
Then run composer update.
