For some time now, it has been impossible to obtain data from third party accounts using SE instagram rules. It only lets you collect data through the associated instagram account(s) you own and from keyword rules using hashtags.
When I create an instagram rule, I use the search button indicating an existing account (@account name) and whatever the account, the search engine indicates that it does not find a match (without results), making it impossible to add any account to follow.
Another fact is that those rules established before this incident started still work but when you access the messages they indicate "unknown author" in the author section.
This is happening to both us and our customers and is crucial to getting relevant data. Any ideas? Could it be that it is related to the new GDPR regulation?
