manta's gem feature sucks but they haven't reached tapas' level of evil.
tapas vanished permanent wuf, they removed the watch 30 ads for 300 inks, they asked for our opinion on what they could improve and they ignored us, they announced some series were leaving days after they left and now they make us buy the "free" episodes, the prices went up for everything, most 3 hrs wufers for comics slowly disappeared
in summation, tapas worst app of the year, every year, until they answer for their crimes.
