Possible sync issue in "All Mail"

[martgil]

Description:

Emails deleted in "Inbox" still shows up from "All Mail", that when tapped to try and opening it will tell the user "thread is deleted or moved". It's important to note that the "All Mail" did a refresh on the first time hence it displays the deleted email in the "All Mail" list. This leaves the user in confusion as the deleted email in inbox should not be in "All Mail".

I initially thought it was working as expected but if we pay attention to detail, the "All Mail" already did a refresh so deleted email should already filter the deleted email and would not lead to such described scenario (not unless its a syncing issue such as the "All Mail" comes on a pre-load state).

Affected FlowCrypt Android app version: 1.6.2
Verified on: Android 13

Steps to reproduce:

1. Open FlowCrypt android app.
2. Go to "INBOX" and delete an email (regular or encrypted)
3. Go to "All Mail" and let it load.
4. It will display the recently deleted email.
5. Find the deleted email and try to access it - it will display the info toast saying thread is deleted or moved.

I tried to reproduce the issue, and the chances are high that it could be a syncing issue. It worked as expected during my retesting, as the app refreshed and correctly hid the deleted emails from "All Mail."

The user also added the following details where emails cannot be pulled from a user created label. Below is the clarification they shared when the error message from the android toast thread is deleted or moved.

No. It is not deleted. It is under a personally created label in which flowcrypt is not able to pull any mail.
It must be due to an update because it was never a problem before.

Emails deleted in "Inbox" still shows up from "All Mail"

It can be a sync issue. It can happen due to a bad (slow, missed) internet connection. For example:

1. Open INBOX
2. Select a few messages
3. Delete them(at this stage these messages were marked to deleting. This operation is asynchronous)
4. Open All Mail
5. At this stage it's possible to see our messages if we have a bad (slow, missed) internet connection.
6. Click on any of our messages from 2.. At this stage, our messages can be already deleted. As a result, a user will see thread is deleted or moved

"All Mail", that when tapped to try and opening it will tell the user "thread is deleted or moved"

But I think this time it's not a sync issue. I've found a bug on my side. Users can't open a thread in All Mail in 1.6.2. I will fix it soon.

This leaves the user in confusion as the deleted email in the inbox should not be in "All Mail".

Agree. But to prevent such a situation I need to use a synchronous logic. Like showing a dialog with progress and waiting for a response from a server about deleting results. After that allow to continue using the application.

@martgil I've fixed the issue and improved sync in All Mail folder.

Agree. But to prevent such a situation I need to use a synchronous logic. Like showing a dialog with progress and waiting for a response from a server about deleting results. After that allow to continue using the application

Let's leave the current logic(async operation: deleting, marking as read, and so on) for now. If we start to receive a lot of feedback from users then I will change the code there to use the synchronous operation(show a dialog with a progress and wait for a response).

Thank you, @DenBond7, for the update. I completely understand.

So far, this seems to be an isolated case. I’ll be sure to inform you if we start receiving related feedback, as it can help us determine the urgency for even further improvement.
