Last week I had the issue that HACS was not shown anymore in the sidebar.
Tried everything (uninstall/reinstall) to get it back, but will not work now anymore. It is visible as intergration but I cannot use it.
Now I have the same problem with Speedtest integration.
Has been working but yesterday I upgraded to 2021.4.0 and Speedtest stopped working.
So I deleted it, and after reboot installed it again. Now the same as HACS, it is installed (partly?) as integration only the configuration cannot be done: error, config flow cannot be loaded.
So it appears I have a problem which stops me from installing and configuring integrations.
