We felt misled on what Tier 2 included. It certainly does not allow for "unlimited" accounts to what we'd believe to be a functioning product. Candidly, I never knew there was a tier lower than Tier 1 so was surprised to learn that other teammates needed to additionally purchase a Tier 1 license at minimum to leverage the functionality at Tier 2 the way it was designed.
When contacting support/sales at both Tidycal/Appsumo, the responses were slow and unhelpful to come to a middle ground.
Though Tidycal is still a better economic choice than a PEPM competitor, i'd advise others to leave ample time to test this solution so that you can get a refund if you don't want to deal with the nuances the more expensive tools don't have.
