Tribunal evidence advice - its only a few weeks away.

Advice please -
Appealed on 26/11/2025, asked for phone only tribunal.
Just had letter today from HMCTS to say tribunal will be 16/02/2026 by phone, so a few weeks away and quicker than expected.

I already sent extra evidence via the upload portal and received a letter from HMCTS and a copy of this evidence, all good.

But about 2 weeks ago I sent my main appeal document - my response to the DWP bundle and have heard nothing back about this. NO mention at all in the tribunal letter

What do I do, the first emails when I lodged the appeal mentions sending extra evidence to an address

HMCTS SSCS
PO BOX 12626
Harlow
Essex
CM20 9QF

This letter today says please send evidence now, the only address anywhere on this letter is HMCTS 36 Dale Street, Liverpool FC

Any advice welcome, thanks
