Promotions are overrated in a remote work world IMO.
Do you want more money? Get a better remote job anywhere else or do something else for money or keep good investments.
Do you want more prestige? For what exactly? You're not seeing any co-workers regularly to pull rank on them and there is no corner office desk with a window to fight for. If you want to be respected in your industry commit to some charitable projects or give talks.
Do you want different responsibilities? Ask, and if you don't get it go find a more suitable job.
