Are there still requirements like pre-authorisation, or Covid-vaccination proof when arriving in Singapore by air?

Entry into Singapore last month was a pain.  Gone is the simple form to fill in and show to I/O.  Now you need to fill in a form which you get on your smart-phone and show that to I/O.  Ownership of a Smart phone is now virtually compulsory if you want to go to Singapore.  Filling in the Arrivals form ' on th IPad provided at Immigration  was a real PITA and then you have to tke a screen shot to I/O to get in the country.

Once Singapore was easy to visit, now it is a real pain and I will not be going there again unless i cannot avoid doing so.
