While the speed has returned to the iPad app, there are problems with the ESV. For example if you go to Acts 17.1 and select the word synagogue for a bible word study you get the lemma for "garden". This is a problem throughout the resource, not just here.
Also, running a text comparison report, previously if I selected another bible from that report it would open the verse being compared, but now opens to the last place I was in that Bible. I use the text comparison report to quickly change bibles versions and get the verse in context.
Please review these issues.
