unable to upload calendar power ups through Cross site tracking

Hello everyone, maybe someone has experience with this kind of problem. 

I would love to connect Trello to Google calendars, but are unable to load any power ups on Trello through to Cross site tracking. This problem maintains after turning it off, reloading the page and even after restarting the whole tablet. 

I already was in contact with apple to figure out what could be the problem, but they couldnt find anything, so now the question here: Did anyone experienced the same and found a solution?

The following is a picture of the message that keeps coming up, no matter what I try.
