If jammy is correct, and I hope it's as innocent as that, then I hope you can see we are all thinking of you @DellaC and I'll be on vinted searching tattle.
I'm speculating, but I wonder whether she's had to hand her phone in as part of the PC Prick situation and she can't remember her login details for Tattle to get set up on a different phone? She might be having to wait until they allow registrations to sign in/register under a different name. Alternatively, one of you private detectives needs to check the local news in Ramsbottom for the past week!
