hot clicks report is available for ours Email deliveries (only condition Channel = Email).
However, for some email deliveries report does not show anything just blank page. For one millisecond this is shown:
It seems that report cannot generate HTML of the delivery due to missing temporary table (but why these tables are needed?). If we open already sent delivery and then press Preview tab and choose some recipient for personalization we get error:
For all deliveries with this error, Hot clicks report is not available as mentioned. For deliveries where this work properly, Hot clicks report is shown properly. This relation does not make sense to me right now but might be helpful for you.
Everything is fine with privileges and other things on report level.
