@Mattw112IG I am not certain if this is a change on Microsoft's end or not, but are you by chance doing an apply to each in the flow? If so, and your SP list contains over 5000 records then you could be maxing out your API calls per 24 hours. Do you know what Power Automate plan you are on? I just had something similar happen in our Environment because I was comparing 2 SQL tables where 1 table had 111 records and the other had 67000 records. According to Microsoft and supporting documentation, I well exceeded my 5000 api calls per 24 hrs! You had also mentioned you are increasing the threshold. Are you referring to increasing the Pagination Threshold? Just wanted to check there.
