Can't upload runs through wi-fi

Hello, my phone runs sportractive and connects fine through phone data but I can’t even log on to the site on my phone through wi-fi, much less upload runs. I have tried deselecting smashrun in the social media settings, revoking sportractive access in my smashrun profile settings, re-established everything, and it still doesn’t work! Getting pretty frustrated. I end up running out of data. Can you help?
