Similar to a similar issue found in the link below that indicates it was resolved, we are now unable to import a larger (approx. 18 MB) Postman collection. We have tried importing through the local Postman client (version 11.6.0) as well as on Postman.com. Same result. Import fails with no indication as to why.
Through testing it appears that collections under 5 MB import without issue. Did anything change recently?
This sounds like the same issue described here that was apparently resolved:
Update: there is a workaround we found. Go to Settings - Data - Import Data. Not sure why that works but it will successfully import a large collection.
This morning I noticed that my Postman version was updated to 11.6.2 and the larger (18 MB) collection is importing in the standard fashion without needing the workaround of going into Settings\Data.
So something appears to have changed between version 11.6.0 and 11.6.2.
