The OP suggested I post my experience with LL as well as it relates to some difficulties deleting albums from LL.
When I want to remove an item by selecting (using my iPad) the 3 dot menu to the far right of the item in LL, most of the time it erroneously takes me to that album’s overview page, not the menu where I can select to remove it. It seems I have to touch the 3 dots in precisely the right tiny spot for the menu to pop up. Any variance from the perfect tiny spot and the album’s overview page comes up instead.
To illustrate, I can get to the LL page no problem either from the Room Home page as you described, or the Roon menu > LL.
When I try to select the 3 dots to the far right of the item in question, most of the time, this is what comes up instead of the menu I need
If I finally manage to touch the 3 dots precisely in the right tiny spot, I get the menu I need
In the past, when it erroneously took me to the album overview page, I would just touch the LL icon next to the Play Now button to remove it from LL. But in the case I just ran into where the album is no longer available, this work around doesn’t work.
