Grapevine is slow again

For some days it started working fine but its slow again.

Issues:

1. Slow loading APIs, mostly comments are slow. Internet is good as other apps work very snappy

2. The comment box is sluggish, either the animation is slow or some other background thing hinders its performance.

3. Posting a comment takes ~1s, sometimes I end up creating 2 comments because of this and have to delete it

4. Not a performance issue: clicking on one notification marks all of them as read

Friendly suggestion to grapevine team Please take app performance as the primary task if possible, we can wait for more features. Also is the app built using react native? Just curious.
