Recurring transactions not saving

Using a self-hosted Akaunting, Version 3.0.6. I was able to save the first recurring expense but any subsequent recurring transactions do not save. The screen shows a bar indicating the saving process move, but the saving process never completes.

I think this is related to this issue on github: https://github.com/akaunting/akaunting/issues/2610

They give a solution for self-hosted, but the issue remains for the hosted version...

Thank you for taking the time to let me know. Still, the recurring transactions are not saving.
