Start resetting devices first. Like phone and laptop. Then change password to social messaging apps and email. Also change WiFi SSID + password. Be patient and observe a bit. If still an issue then engage police again.
Zoom used to be good. It’s a mess since they’re trying to be a product suite. Feels like the app is run by 4 product teams with the following team names:
Top Navigation
Bottom Navigation
Left Navigation
Right Navigation
Their web interface is great too. Faster than Thunderbird in my experience (I tried the latest Thunderbird on Windows yesterday on a relatively fast PC and it kept pausing randomly all the time)
Deliverability issue are foreign to me. Never had an issue in over a decade. Did you configure everything properly? Also, ask their support about this with a concrete example. They’re very helpful.
Thanks for letting me know, I wasn't aware of that, unfortunately I would need Premium API access to support cashtags and hashtags (I opted for the free plan...)
