Problem:

The topology on the map shows the wrong setup (https://omada.example.com/#mapEntry) or the setup is jumping into different configurations. Sometimes correct, but generally wrong.

Description

Today, I added a loop to my existing setup and configured RSTP. The connections are shown correctly on the devices and initally on the topology screen. After a few seconds, the topology screen changes to the wrong topology. The devices show the correct port settings and the correct port blocked for RSTP so it seems to be a display issue.

Physical topology (port in square brackets):

Internet <--> ER7206 [5] <--> [2] TL-SG2428P (Location G) [1] <----------------------------------------------|  (connected to the device 2428 (Location D) below, I have no down arrow)

                                   [6] <--> [8] TL-SG2210P (Location K) [1] <--> [2] TL-SG2428P (Location D) [1]

Actual topology based on the ports (been shown once or twice when waiting long enough. Refreshing the display jumps straight to the wrong image)

Internet <--> ER7206 [5] <--> [2] TL-SG2428P (Location G) [1 disabled by RSTP]

                                   [6] <--> [8] TL-SG2210P (Location K) [1] <--> [2] TL-SG2428P (Location D) [1 Active]

Displayed topology

Internet <--> ER7206 [6] <--> [8] TL-SG2210P (Location K) [1] <--> [2] TL-SG2428P (Location D) [1] <--> [1 disabled] TL-SG2428P (Location G) [2 Active]

Also interesting to note is, when enabling the "Link Labels", it does show different ports than the displayed ones for Location G. The link between Location D and G show Port [1] and [2]. Port 2 would be the correct port that is in use but connected to the ER7206.
