FeatureTable.addFeatures() does not complete (sometimes)

Hi, I am observing something unexpected with an app here. When I add features, sometimes, the addFeatures does not call onSuccess or onFailure, nor does it throw. I was wondering if maybe there is some way to detect what is going on?

basically I get my featureTable and call addFeatures with a List<Feature>, no magic there.

I am not seeing this on small amounts of features but it happens too often on lists sized 9000+. Is there a limit I should be aware of, should I split and perform the operations on chunks of 500 instead or something like that?

Tried with chunking features into blocks of 500, but still seeing the issue. Even tried with a delay after each pass. Im doing beginTransaction before the whole operation and commit if everything went ok, if I detect an error I call rollbackTransaction. Which doesn't help since it seems to get stuck somewhere - sometimes.

Apparently, it seems to be stable when reducing the size of chunks to 250, so far.

So if anyone does custom hard sync, as in: deletion of features followed by large amounts of features passed to addFeatures, maybe this will help. Chunk it up.

Correction: It happens still. I will test more, if anyone knows of limitations, it would be great. I am doing deletion before the addFeatures so maybe I am too quick here. Will update.

I believe the issue is not related to the SDK at all, which might not come as a shock. I now think it is a good old async related issue.
