I wanted to frame a sentence with "Most importantly"
Can I use "Am Wichtigsten ist" or "vor allem sollte"? I am not sure which one is the correct solution.
For example, I want to convey in a letter the below sentence:
I want an explanation about your delay in two days. Most importantly the delivery should not be delayed next week.
Can I frame it like:
Am wichtigsten ist, es sollen keine Verspätung in kommenden Wochen.
I constructed this sentence on my own and hence please bear with the horrible grammar if any.
