Microsoft EmployeeTo clarify, are you seeing the Warning icon show up in the Visual Header, with text "Style preset not found"?
This is likely due to double-wildcard stylePreset value in your theme file, like:
"*" {
"*" {
"stylePreset" {[
"name": "Flashy Rows"
This used to only apply for Table and Matrix, which shared the same stylePreset options, but now we will try to apply this to all visuals. Since many visuals do not have a stylePreset defined, it will fail to find one and warn you about this. stylePresets for all visuals was just released last week. We will consider only showing this warning in Edit mode, it is not that useful for read-only users.
To fix this, use visualType names specifically for default stylePresets and re-upload your theme.
Note: the latest theme schema update has made validation a bit more strict, so you may need to fix other errors before you can upload themes you have used in the past.
