I'm not sure if I'm using Blocks instead of Views (because I'm adding a View in the Block Editor, a bit confusing).
The terminology is a bit confusing, since these terms represent both plugins and features. Basically there are two plugins - Views and Blocks. Views has been around since before the Gutenberg WP updates, and Blocks has been added recently to fit in with the new Gutenberg WP workflows. Right now, the same core functionality exists in both plugins with a few different configurations (though as you have noticed there are some missing Views features in Blocks that we are trying to add as soon as possible). In the future, Toolset Blocks will be the preferred plugin where new features will be added. A block is one element in the block editor interface (a.k.a. Gutenberg). A View is a listing of some kind of posts, taxonomy terms, or Users. It can be built in the classic Views editor or in the blocks editor. Hope this helps clarify a bit - feel free to create new tickets to discuss any confusion you may still have.
But I can't disable the option to not show the results on the same page.
Typically this indicates that the View was built in the Block Editor rather than in the classic Views editing experience. To get to the classic Views editor, check the Toolset menu to see if there is a "Views" submenu. If not, you must go to Toolset > Settings > General tab, then choose "Show both the legacy and Blocks interface and let me choose which to use for each item I build" in the Editing experience options. Then you will see Views as a submenu of the main Toolset menu item. You can build a new View here with custom search filters, then use a View block to implement the View in the Block Editor with filters and results split into separate pages as shown in my previous post.
UPDATE: Found a way to show these places. Open them and click "Update". Any thoughts on why? The original posts/locations where created by a non-admin user.
Hard to say for sure offhand, but my guess is that the location was not chosen from the Google autocomplete input field. Instead, maybe the User typed something freehand and clicked "save" without choosing from the autocomplete options...maybe? Then when someone edited the post, the maps location field autocomplete was able to guess based on that freehand input, and a properly geolocated address was saved. I would need to know more about the original input, the View criteria, and so forth to give you a more concrete reason. If this continues to occur, let me know and I can split off a separate ticket for more in-depth investigation.
What am I doing wrong? How do I add a link to anything in the block editor? How do I go from one item in the result to the item itself?
If you want to add a link to the post in the results of a View, you can place the Single Field block in the View's loop. In the field source configurations, choose the Standard Field option and "Post title with link" from the current post (see post-link.png). Another option is to use the Fields and Text block, if you want to add more text and format a link inside some other text. If you want to create an arbitrary link to some off-site webpage, use a paragraph block, highlight the text you want to make a hyperlink, and click the link icon that appears above the paragraph block (see arbitrary-link.png) to configure the link destination. If you want to show a link to some URL that is held in a custom field on the current post, again you could use the Single Field block but choose "Custom field" instead of "Standard field" in the field source configurations.
And now my View has gone and is replaced by a complete different View! While the right view is still visible in the editor, the wrong one is shown in Preview and normally on the front end. This is annoying!!
May I log in and take a look to see what you're describing? Hopefully this is just a minor configuration issue and not indicative of a bigger problem. Please provide login credentials in the private reply fields here, and let me know where can I see the problem in wp-admin.
