FYI, I see this error when using the plugin:

Notice: register_block_type_from_metadata() was called incorrectly. Block “tiles/progress” is declaring fontSize support in block.json file under supports.fontSize. fontSize support is now declared under supports.typography.fontSize. Please see Debugging in WordPress for more information. (This message was added in version 5.8.0.) in /srv/www/wordpress-one/public_html/wp-includes/functions.php on line 5663

It’s possibly the reason why, when I tried installing the block plugin using the editor’s block search it failed to install the plugin. Though that could be a separate issue!

I just found and installed this plugin and love it! The only problem I’m having is that if I register a custom color palette for the Gutenberg editor and then pick one of those colors for the progress bar, the color doesn’t show on the published page. It works fine if I choose a custom hex color, though.

Greetings,
I must say, your plugin arrived at the most opportune time.
One question though, how can I hide the number, in this case, the percentage?
Keep up the great work and all the best success in your endeavours. ??

This part of the HTML generated from the block looks like:

<div class="wp-block-tiles-progress__background has-background has-primary-100-background-color" style="background-style:[object Object]">
