[Bug]: MQTT messages bug on Android and WWW

Hardware

Heltec V3

2.3.10.d19607b

Description

Hi,

problem is existing on 3x Heltec V3.1 nodes: 2x ROUTER_CLIENT (WiFi+WWW) and 1x CLIENT mode (BLE+Adroid app). All flashed with full erase, with newest available stable FW (Meshtastic Firmware 2.3.10.d19607b Beta). Also, I turned off serial output.
The issue is only with MQTT, I haven't seen lost messages in LoRa (or maybe it's hard to catch).

Server: mqtt.meshtastic.org
MQTT group with 10-20 active nodes (~60 in total (not active), maybe 5 sending something from time to time).

What's happening:
Device OLED shows all messages correctly (I think, it's not 100% sure).
Node WWW page shows no messages, and after few hours there is like 3 of them.
Node Android app skips some messages, I'd say it's like about 10% lost.

This is quite frustrating, because I'm loosing information... even 10% loss on Android app is really bad.

If you need some additional info or specific tests and/or logs - I'll try to help.

BR, Doman.

Update;

1. Don't use Android and HTTP opened at the same time - device can't handle it, and looses information.
2. On Heltec V3.1 (and probably all other Hetec devices), if the node count (NodeDB entries) exceeds 80, the device starts to struggle and shortly after becomes overwhelmed. Avoid big meshes with Heltec (over 80 active nodes). On LILYGO T3S3 I don't have this problem - maxed out NodeDB (100 nodes, all active), sending messages constantly - no problem, all are showing.

Case closed.
