Got a solution from PBI support.
========SOLUTION TEXT STARTS========
One easy way to solve the ussie is to transform the date from a text to a date value using the UK format:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fVRRcsUgCLxLvjsjYIzmLJl3/2tUGht3ie2fDALLsnBdW9YkOZnosX2+rq2/b7P+mFmSnNPbTbVp6p5k589o9sxtmnYO7x1rNamAaUkVzJbEZmx/S4FUQiDde4C3cCGODf32ovjZG0QYQrFaBhuj7jG8a3IOQiV7LHR7x+dzcPWQI7rAPFI1guFeZXJWsZMNgPEQO2BkBqmMqr3mC6i8BeBKAlfGQgqx/Fm5bpcZSkUbNRhEqCwzhwGpfAoVUhWObaRYBwnkOO2V2QCJ2q939FtfTJZF3SkzYxh10dEwhToKG/rmmTR5siYZZCQnaLKwzCphDgNdaANbMDKDroRX0jVZmEnWBtGe+W4odRRQ9bq47GH3+5vMzCDfV+XvI+MwYNnDJQw89/HhBMOdjKdAaXF8KCezAXXjuHk1/F7xqaeRFa57EDmO2f5lA2b0HNUe+/kG", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Date = _t]),
#"Changed Type with Locale" = Table.TransformColumnTypes(Source, {{"Date", type date}}, "en-GB")
in
#"Changed Type with Locale"
In the Query Editor > Advanced query editor, you have to replace your
#"Changed Type with Locale"= ……………………………….” (whatever is there in middle), please replace this with the below one and close and apply and now run the DAX query will work
#”Changed Type with Locale” = Table.TransformColumnTypes(Source, {{"Date", type date}}, "en-GB")
========SOLUTION TEXT ENDS========
