r().sortable is not a function

[sir-gawain]

With powermail 13.0.2 and typo3 13.4.4 i get an error "r().sortable() is not a function" in the backend module.
I think, this has something to do with the queryui integration, that changed in the past. The same function is defined in powermail 10.7.4 and typo3 11.5.27.

Can you try the latest powermail version and give feedback?

Did you change the backend templates? There were some changes between powermail v10 and powermail v13.
