Sorry for the late reply! I’m very glad to hear the OTA went well. I’ve stopped using tracker control for now, I’d prefer to use a VPN, and be sensible about what apps I do install, and run a hardened version of firefox for browsing. I also don’t use the mail app! I hope by now you have found another user who shares the issues. Even if you haven’t, they’re great for the /e/ team to be aware of, so they can squash the bugs in the next update.
