The auto updater is not working at the moment,
I have notified Lance, most likely he did not have it be an “auto update” because it w0uld break something!
but after you update SLP to 4.7.3
1) Download from your account EXP 4.7.3 as a zip file to your computer
2) Deactivate and delete Experience 4.7.1
3) Upload and activate the zip file it will be 4.7.3
Lance published the release notes on 4.7.3 Experience and SLP in You Tube if you want to check it out, haven’t done a post as yet.
P.S. Make sure you have a back up as usual.
Let me know if you have an issue
