5 stars if I wouldn't have a weird bug where it always forgets the servers. I have to add them every time I start the app. Notifications work though

Bring back the history on the free tier. We're not even using your servers for hosting. Paywalling important stuff for no reason is completely against the whole open source nature, especially since you've got so many free contributors.

I am using Samsung Galaxy M21. I have been trying to log in for 10 days, but I am facing a credential issue. Although I am using it in logging in a laptop with the same credentials and it is logging successfully. Can anybody help me ?
