Last week we updated to AdRotate Professional to 5.6.1 and now our ad groups, set to block mode, are not refreshing with a page refresh. We have to empty the cache to see new ads. PHP is 7.0. WordPress was just updated to 5.3.
Dev environment is working fine with AdRotate at version 5.2, PHP is 7.0 and WordPress at 5.3. Please advise.
