Hello Leo and the team,
I have been having problems for a while now when trying to create new passages. This has occured on both the chrome and firefox browsers on a Windows 10 computer. I will add the text, enter all the relevant details in the sub-headings and then click either 'save and open' or 'save'. The 'processing' icon will start to turn and keep going on indefinitely without completing the task.
In the attached image below you can see a few texts that I have attempted to add where the process has not been completed fully. When you click on these passages there are no words visible.
