To be honest I don't think anyone has any issue with her seeing Tyler in general, it was more the fact that she blatantly went up to the Lake District to see him then came back which is a break of the rules by crossing tiers. If she went up to the Lake District and stayed with him for a prolonged period fair enough, or if he even came down to Brighton on his own and stayed at hers fair enough but it was the fact she left Brighton went to the Lake District with him, took photos with fans maskless non socially distanced, pretended she was still at home then came back to Brighton is what angered people on here. No one has an issue with them seeing each other it's more of the fact that if you are both from different parts of the country (and different tiers at one point) than one of you needs to leave home and stay with the other not both of you going back and forth to each others homes.
Tyler is now staying with Saffron and her family which is fine (and according to the rules he won't be able to go back to his home up north) but people think that they will not adhere to this as they are not as active on instagram and social media and are probably hiding the fact that either Tyler on his own or the both of them will be going back and forth from his home to hers.
