Spare Battery Availability for HMD Skyline

Has anyone had any joy in getting a replacement battery for their Skyline phone? If so, when did you get the battery? Where did you get it? Ifixit don't have any, don't have any on order and say themselves the wait will be unreasonable. Gsmnet don't have any and even a trawl of random sites on the internet isn't bringing any up.

Can't believe I bought a self repairable phone from a manufacturer who doesn't supply spares to the public or their repair partners. I would never touch a Nokia/ HMD again!
