So the drop thing is great (I think) and when I did a free ride last night it was ticking over quite nicely but after 30km I notices that the level does not progress anymore. Is this the design - for drops to replace the level progression or is it a bug?
XP should still exist and you should still be able to level up. AFAIK Drops have not replaced levelling up, they are just different so seems like a bit of a bug.
