I installed Gboard to get the Japane IME support. I let the Network and Sensors permissions ON for now. To function properly for Japanese (i.e. suggesting Kanji based on Hiragana input), Gboard needs to download some dictionary or Japanese language pack.
However, even though I allowed it to access the network, when I type something in Japanese, I get a message to tell me that Gboard is not allowed to download the Japanese language pack.
I tried both on Wi-Fi and LTE connection with no avail. It is as if the app got no network permission regardless of the settings I chose.
