When the Tapo D235 v1 EU doorbell detects an event, e.g., a person or animal, and I click on the notification, playback from the MicroSD card freezes for about 10 minutes and it is not possible to view any recordings at all. During this time, live playback works correctly for a moment, then freezes for about 10 seconds, after which it returns to normal, but playback from the MicroSD card still does not work. The doorbell is connected to a constant power supply via an 11.5V/0.8A transformer. The MicroSD card is: Kingston Canvas Select Plus 128GB MicroSDXC I C10 U1 V10 A1. RSSI of the doorbell with an access point at -52dBm, QoS priority on the router set only for this doorbell. There are no problems with live playback or recordings, the settings load correctly, there are no problems with calls even when away from home, it rings phones correctly and the call quality is very good. The problem only occurs after an event is detected and after clicking on the notification right away - playback from the card does not load at all, even after resetting the application (the same problem occurs on Android), only one person is trying to play the recording at that time, there is no situation where two people are trying to connect at the same time, and after waiting 10 minutes, everything returns to normal and recordings can be played normally. While the doorbell is frozen, everything was recorded normally and the recordings are visible. My phone model is iPhone 16 Pro with iOS 26.1, the doorbell firmware is 1.2.1 Build 250926 Rel.64362n, the iOS app version is 3.15.103, the access point is Tp-Link EAP110 Omada with firmware version 5.1.3 Build 20250709 Rel. 67038(4555) 2.4ghz network, speedtest average 40Mbps download and upload on the phone, but the internet should not be a problem as the issue only occurs after an event is detected. Additionally, the day before, in the playback option, after about a day, the event disappeared when someone rang the doorbell, the event marker disappeared from the timeline, and the moment appears as a recording but cannot be played back, the image is frozen without sound only at that moment. I formatted the MicroSD card twice and factory reset doorbell but issue still occurs.
