To anyone else reading this with Support Account login issues, having spoken to a moderator - apparently the old help desk was completely removed some time near last April 2018.
Also apparently all Support Accounts were completely removed during that time, which if true would explain my login troubles.
If a moderator is reading this - I think it would be a good idea to post this Support Account removal reminder which I imagine will cut down on Yoti trouble when people will inevitably need support accounts given how unfit for purpose Yoti’s system is - for example Yoti will not accept my EU Member State Government issued valid in-date photo, name, address, d.o.b. I.D. (this is not due to questionable document - it’s due to the Yoti automated system not being configured to read my document format, a document which millions of people in my country have. Note: Yoti do not have a workaround mechanism in place to allow Yoti Support to manually approve documentation I.D., which is pathetic.
A Yoti Support (in use the term loosely) sent me this: “Our tech team are working to make sure we have these templates in the app to allow us to accept a wider range of ID documents. Fingers crossed this will happen … soon.”)
A note at the Support Account login / register page - alerting old closed (circa April) support accounts would save people the hassle of trying to recover now deleted support accounts.
I think it best a moderator make this thread as their status will lend added credence to the alert.
