After some search I found that footer.php is not displayed,when logged in. Logged out everything is okay. Any important changes in the 4.1 in the way the template parts are called and rendered?

I could solve the problem. Had an APC Cache running and an older APC Object Cache Backend. Installed the latest version (https://wordpress.org/plugins/apc/ – is there any alternative since it is not continued?) and the admin bar was there again.

I am having the same issue, but I am not using any caching plugin and I am hosting my WP MU on Godaddy.
Hosting might not be the problem but the template. If there is some error in the main template, the footer.php will be not loaded and it is responsible for the admin bar. Check if there is a condluding <body> in the HTML output. If not, the footer and with it the admin bar will be not there.
It is not the footer, I can see the “Proudly powered by WordPress” in it. Also after inspecting it the footer looks fine in Chrome dev tools.
From time to time I will see 500 Internal Server Error and I will have to reload the page to get to the site.

I am also having issues with pre-viewing my draft posts.
I thought it might be the .htaccess, but I updated that, and it did not fix the problem.
Any other ideas?
So I finally decided to turn off all plugins and try to see if one of them is breaking the site. It was Google Analytics by Yoast. Turning that on kills my toolbar…
Hope Yoast gets that fixed soon.
The Google Analytics plugin by Yoast also is breaking LDAP authentication when using wpDirAuth plugin. Deactivating this plugin solves both the disappearing admin bar issue and the LDAP authentication issue.
Thank you for that update. I had that same issue. Deactivated the plugin Google Analytics plugin by Yoast and voila, Admin bar is back. Please let me know if you find a better alternative for Analytics.
Thank you.
Thanks a lot for this update. it was also breaking my woocommerce site. Impossible to connect to the customer (or admin) woocommerce account.
Thank you !
Yoast have released a 5.3 beta that fixes the Toolbar and some other issues.

I cannot speak of other issues, but it does fix the frontend Toolbar issue for me.
