Decent app but occasionally still unreliable
It does do a good job 95% of the time, but when it glitches you don’t know how much you should trust it. One bug that still happening, after many years and many reinstalls is that email read status would be inconsistent across the app. Switch to “Promotions” all read, switch to “Primary” and the same emails you just marked read appears as new and unread. Similarly the counter sometimes out of sync. As if Facebook’s many years long failure to fix notifications caught out the developers at Google too. It is rather disappointing to see such technical prowess fail for so long at something (on the surface at least) such simple. Unfortunately this just makes hard to feel like this app is reliable.
