Hi Thomas,
I think for this scenario a SAP_BASIS upgrade would be ideal
You will need to open an Incident with the BC-DWB-TOO-WAB to confirm but first look at the following notes as an example of notes that have SNOTE corrections for the ITSmobile Visual Editor
1873703 Improvements for the initialization of the graphical editor
2176355 ITSmobile Visual Editor: Switching templates during start results in error
this is just a small sample of note corrections since SAPKB73107
Regards, Oisin
