I am importing a csv file with 1 term set and approximately 12,000 terms. When I begin the import, it says something like "Please wait while we import your terms", and about 5 minutes later the popup windows says "Unable to display page". When I refresh the page my term set is missing approximately 2000 terms. According to Microsoft documentation I thought a term set can have a maximum of 30,000 terms so I am not sure what is going on? Is my request timing out?
The structure of my csv file is something like this, I changed names around for anonymity:
Specifically I am noticing after I refresh the page that the "IMP ID" (and all of its child terms) are not in my term set.
Thank you very much for your help
