We have built a partner community using the Visualforce & Tabs template. We now want to find out if Salesforce1 is a viable option to perform certain actions our users want to do from a mobile device.
I've worked through all steps from the documentation, and I'm able to log in, but I am then redirected to the Classic interface:
PS1: Documentation states the following, but doing so also just rerenders the page in Classic in my browser (while this does work for internal users):
Without this setting, community members must append /one/one.app to the community URL (for example, https://universaltelco.force.com/customer/one/one.app) to access the community via Salesforce1 from a supported mobile browser.
PS2: Not sure if related at all, but I cannot find this setting anywhere. We are using a custom login Visualforce page and redirecting to a next Visualforce page after that, which seems to be working fine.
