Woof, yes! Though I'm glad Heroku remains, and I ought to also be glad that it has been stable all these years, …it's clearly neglected.
The very first interaction I have with Heroku is a two-factor sign-in, and …it's this horrible page hosted on salesforce.com, which doesn't have retina graphics (i.e. is blurry on screens Apple have used for 15+ years), doesn't work properly with automatic one-time-code generators (because the login form is heroku.com, but the two-factor is salesforce.com), and …gah! What a mess. Thankfully you fall through into the pretty, well thought-out Heroku dashboard of yesteryear.
Oof, hard disagree. I absolutely hated writing Objective-C for years– I felt like I had to write unnecessary 'glue' with header files, handling of 'nil' was always jarring, and square brackets at the start and end of every call felt horrendous, to me at least.
I relished the day Swift was announced, and have been using it ever since.
The support chat transcript is so uncomfortable to read– the person on the other end 'at Three' (aka a contact centre on the other side of the world, contracted out at the lowest possible cost) might as well be a bot, but the chat reads as if the person at Tutanota genuinely thought that they were chatting to a logical coherent human.
Having used Three UK on and off for two decades, this support chat lines up exactly with how I remember– 'robot humans' that say any ol' tosh to finish the contact session.
Avoid Three.
FWIW: all UK consumer telecoms services seem to have horrendous contact experiences (Though Three, of the prominent handful of providers, tops the charts in my opinion), but I've used EE for the last few years, and it has been consistently solid and fast, and thus I thankfully haven't /needed/ to contact anybody there. I cannot say the same for Three.
Their offering perfectly fit the bill for what we needed, but they turned us away; citing a requirement of transacting €5M per year, despite us needing a payment handler /for launch/.
Anecdotally: I've been looking to get answers from Stripe, about fees-related questions that either make my proposed use viable or unviable, and I've received nothing but copied & pasted email replies, a week+ later (or not at all), which essentially ignore what I've asked. Incredibly frustrating.
When I mention the experience to friends, they joke that I have Stockholm Syndrome; to want to continue pursuing them, despite their complete disregard.
