I installed PlugOS App on my Xiaomi Redmi 15 and pressing the blue Agree button does nothing.
Kill the app and try again, or you may upload a screenshot / record, let me see your issue.
I did and also re-installed. It is like the GUI is frozen.
I will try to repro this issue. And you may try it on another mobile if needed.
Thanks! Stupid me, I overlooked, due to bad eyesight, to check the (for me invisible) white box on the left, then AGREE worked.
