Hi Claire, 

Thanks for trying that, to troubleshoot the connection please try disconnecting and reconnecting the account (make sure you've reviewed all transactions in the For-Review tab before doing this, as these will be removed when the account is disconnected). 

To disconnect, go to Accounting > Chart of Accounts > Select the drop-down to the right of the account > Edit > Tick 'disconnect this account on save' and save.

After this, go back to the Banking tab and reconnect the account as new by selecting 'Add account' and searching for Paypal (UK).

Please get back to us below if you're continuing to have problems after this. :smiling_face_with_smiling_eyes:
