Richard,
I'm afraid I can't remember in detail everything I did back in the early days of my Sovol.
I did have a few issues with bed adhesion and filament jamming but much of this was really my own inexperience (not getting the bed level right when checking it!)
I tried all the recommended things to solve the bed adhesion issue (Pritt Stick, Blue Tape etc) and just managed to make a mess of the bed. The heated bed does need to be well cleaned (whilst cold – I use solvent) – and then NOT touched (e.g. no fingerprints etc). But that's all the Solvol needs apart from careful bed levelling (and the correct material settings in Cura).
Out of the box, I'd managed to print the XYZ cube test print quite nicely but then somehow seemed to lose my way a bit (hence the Pritt sticks etc). It finally dawned on me to check the Cura settings, Sovol themselves had used on the 'XYZ' test print and use them with the filament supplied. Bingo, everything worked perfectly again.
The other problem was filament getting jammed in the extruder between prints. Sovol have a YouTube that explains how to clear this problem if it occurs and as usefully (prevention being a better strategy) some G-code to fully withdraw the filament at the print end.

You can see the recommended G-Code fix at 2:20mins.
Stick with it and I'm sure you will not have too many problems once you get used to things.
