As of 2020-04-16 we have retired our legacy strategy infrastructure. This means that data about picked matches prior to 2020-11-20 will no longer count towards your strategy history totals (total picked matches, hits, misses, and strike rate). 

Those old matches were already absent from all exported spreadsheet files, so nothing changes there.

We understand this may be inconvenient but this is an isolated event and an inevitable part of our effort to improve our service reliability. This change allows us to greatly improve our strategy-related features.
