Sorry for the late reply. I can understand your points. I do understand that Stripe is a major point and at this moment in time we do not support this and it is not something we are able to provide in this moment in time. Till integration is also another thing that we do not support and that is not on our roadmap at present I'm afraid.
Open banking is something we are actively developing at present and that we will be in a position to offer by the deadline date. So for this we can say with certainty that we will be able to provide this.
We are also developing a new API that will provide the opportunity for further integrations.
Finally, we have just completed development of our new mobile app which was our most popular feature request of late.
If you do decide to leave, I wish you all the best and I hope that all your future endeavours are successful.
All the best,
