Same here, it's in My Menu, but it's still a rather convoluted means to activate the Wi-Fi.
I'm curious how you're able to transfer files without going through the Canon app; the camera won't let me transfer files until I open the app on my phone. It probably has something to do with how you've setup the phone as a hotspot and the camera joins that network, whereas I go the other way and have the camera start the network and I join my phone to that. I don't do too much transferring to my phone, so only the wi-fi is only activated when needed, versus being turned on all of the time, which would drain the battery.
After you configure the web services for the camera and transfer the configuration over to the camera for future use, it shows up with a web service icon as a selectable option.
For Google Drive, the icon is the Google Drive icon. I turn on my camera as a hotspot, then click this icon, and it tells the camera to connect to the last wifi router (which is my phone), and through the hotspot, it connect and authenticates to Google and then starts the image selection and transfer on the camera.
Basic steps: (http://support-th.canon-asia.com …nts/TH/EN/8201758000.html
)
Log into Canon Image Gateway (using my Google account)
Register my 5D4 there (might have had to plug in my camera to the laptop at this point, don't remember)
Set up the Google web service, put in my Google acct authentication info
This will get downloaded to the camera either through a cable, or when the camera connects to the internet (through router or phone)
At this point, I now just click the google drive icon, it connects accordingly through the router (or my phone as a hotspot), and then presents all my images for me to select and tell it to transfer when I am done. I do this periodically through a game, all through the camera. My phone never sees the light of day during image select to send to the social media group.
Facebook, Flickr, Email, and a myriad of other options are also supported in the same manner. This is one of the reasons for Eye-Fi demise.
