I'll add that I'm baffled by this.
It can take minutes (yes, minutes) to open a simple note, or a notebook or tag, loses edits that you make, all while pinning my CPU at 100%. (4GB RAM, 8 core CPU.)
AFAICT, the conversation currently goes "you're ready to upgrade to the paid tiers? We fooled you, we aren't remotely close to providing a paid level of service."
Grrr.
I've tried reinstalling, and it clearly retains the data (possibly corrupted?) from the previous install because it takes no time on the initial sync. My first install got to about 5% sync after 24 hours, so something is horribly screwed up. Yes, I've turned off the android option that retains app setup during uninstall.
