Like many here, I've been fighting with the AliExpress app popping up when using textra. Working with Textra support team was absolutely useless. I did learn it is the ads Textra uses causing the issue, so the bandaid solution is to block ads.
Here is how I do it on my Pixel 8a in the network settings:
-goto settings, network & internet, private DNS
-select private hostname
-enter under hostname: dns.adguard-dns.com
-done
Enjoy Textra and Aliexpress not being a POS
