Doc insertion from multiple apps at he same index

[zabakala]

Hi. Thx for this great project. I have a question relating to inserting docs. When two users synced to the same collection insert a record to an array field at almost the same time, the insertion index becomes the same and one of the 2 incoming records ends up overwriting the other as they are being inserted simultaneously at the same index position. Is it possible that these cases are not covered?
