thank you.
after a bit of a think, I think this may take me longer to implement and test than I initially thought.
so, the process is as follow, the way I see it now, at least....
1. user submits form
2. add user name and submission date to a list
3. have a flow running, say, every 2 weeks, for checking which users have a submission date > 1 month
4. send an email to those users
5. delete those users form the list. this is so that I do not email them again 2 weeks later
so, I will be using a temporary list that gets dynamically updated as users submit forms and emails get sent.
which is the best action for me to do these checks on a Sharepoint list and edit it? any recommendations?
