Many technical errors and disqualification the past 2 weeks. At least now they would manually issue credit, though sometimes only partial credit if the system does show you spend considerable time on the survey. That is a bit better than previous practice that completely denied credit when disqualification happened at the end of the survey.
May be they are trying tactics when participants becoming too discouraged and no longer taking surveys as frequently as in the past therefore not enough survey results to fulfill their contracts.
