Is anyone else struggling to authenticate their Co-operative Bank (UK) bank feed?

Several users had the issue in 2023 but Co-op resolved the problem. I've been struggling on and off for a few weeks. It randomly works once in a day, then stops. At the suggestion of The Co-op I removed the consent in the Co-op portal and reconnected, but it didn't work. The latest from the Digital Team is:
“The expiry date for a consent is no longer being sent by our TPP provider (Token.IO)  - but we are still trying to display it (it defaults to a UNIX default timestamp of 01/01/1970, when it gets no value provided)
 
I think CapG, do have a fix ready I believe to stop showing this expiry date completely – this would not affect functionality of QB
 
I have again, synced our production test accounts today, with no errors at all in Quickbooks.  So it might be worth asking the customer to try deleting the existing consent, and re-adding their accounts in quickbooks, and then raising a ticket with quickbooks if the problem continues, so quickbooks can then open a ticket directly with Token.IO, for this customers issue.”
Please help!
