I have been using the extension this year for 1 month. I then canceled my subscription.
I can’t use the extension fully because a pop-up always asks me to upgrade my subscription.
And if I go into /settings, this is what it does:
When i try to activate my subscription it only restarts the page and that is it.
I am sure I checked on all the tabs of the documentation that can be found here : Language Reactor.
Thanks for your help
