Thanks for that - did as you suggest, and even with Dataview on its own (i.e. without any community or core plugins enabled), it would hang on both devices. Even thought a rogue theme might be causing some issue, so went with none but still a problem…
I’ll post an issue onth Git page as you suggest, but would be interested if anyone else is getting the problem. BTW, is there ayway I can acccess the previous version of Dataview does anyoen know?
