Failure to update Lightroom Classic on iMac.

I have a long standing account with Adobe. Recently I changed plans from ‘Photography plan’ to ‘Lightroom plan with 1TB’. Now I would like to update the Lightroom Classic software to the new v.14 however it will not provide the update. It appears there is a billing issue. The account was last paid on 22 March according to my account tab on the web part of Adobe. This is an annual plan paid monthly.
On the next line of text I can see that the Adobe system is waiting for the old plan ‘Photography plan’ to be paid and that there is a ‘billing issue’.  I no longer require this plan. I thought I had stopped it. There is also a line of text saying there is $0.00 monthly owing. But this is stopping Adobe from providing the Lightroom Classic update to v.14.
Could someone advise how I might get ‘off’ this Photography plan and allow Adobe to update my Lightroom Classic as part of the already paid for ‘Lightroom plan with 1TB’.

TIA
