After battling with it for hours… You can upgrade the component, the depecrated message should be gone (I couldn’t upgrade on the latest version today, but I don’t have the deprecated notice anymore, so the banner should disappear too) and we should be good for a few months, until Discourse changes everything again
The changes should be seamless on your forum but let me know if you have some issue!
The work by @Arkshine on the previous version and @lhc_fl on her component helped me a lot
