Spark Mail: AI Email Assistant — Great app, terrible update

Please bring back the centralized toolbar, the new off center version is terrible.

Every email has to download while you open it so you have to wait and if you're not on a super fast connection, it is painful.

There are some other visual adjustments I wish could also be made to customize.

I pay for the app and am constantly in situations where the schedule meeting doesn’t show up in calendar.

I wish it had support for inline HTML in the email editor, but it’s not necessary for me on mobile.

Spark Mail: AI Email Assistant — Too much bloat

With every update, I waste a few minutes trying to figure out how to disable some new AI feature and obtrusive inbox sorter.

Spark Mail: AI Email Assistant — Bloat bloat bloat. Unreliable.

I cannot count how many emails I have missed due to the app being broken and not notifying me of email arrivals.

Spark Mail: AI Email Assistant — Good app with limitations and bugs

Also, on full day events, when there are multiple events it only shows 1 by default not multiple which is a poor UI/UX implementation because it makes the user do more work to see if they have multiple events.

Spark Mail: AI Email Assistant — Downhill

I pay for the subscription but will probably cancel.

I used Spark for a few years and finally determined that apple mail is better for me, not because apple mail has been improved but because Spark has become more bloated.
