I am currently developing my first website using Craft 3 and I'm loving it overall. I seem to have a small issue that I can't quite figure out. When I go to the updates section in the admin panel, I am proposed multiple updates to Craft and 2 of my plugins (see screenshot). However, I can't figure out how to actually do these updates! According to this page in the docs, a button should appear at the top of the page.
I've also tried via composer :
composer update craftcms/craft, but it says 'Package "craftcms/craft" listed for update is not installed'.
And I've tried :
composer update craftcms/cms and that gives 'Nothing to install or update'. Same thing if I try to update plugins such as redactor that way.
I had started out on RC14 and I was able to update to RC15 properly via the button, but since then, the button no longer shows. Since I am new to Craft, I am not sure which log would contain pertinent information for the problem. I will be glad to share some logs if necessary. If it changes anything, I purchased a Pro license before the license changes on Apr 04.
Sorry if this is a noob question, any help is appreciated!
